===Clone Cell Style===
 +
To keep original cell style and only modify part of style, we can use the <javadoc directory="zss"  method="cloneStyleFrom(org.zkoss.poi.ss.usermodel.CellStyle)">org.zkoss.poi.ss.usermodel.CellStyle</javadoc> to clone a cell style.

===Prepare===

<source lang="java" highlight="2,3">
−
1. User's selection range<br/>
 
−
We need to know user's selection range to set style. We can use '''onCellSelection''' event.
 
−
<source lang="java" >
 
−
spreadsheet.addEventListener(Events.ON_CELL_SELECTION, new EventListener() {
 
−
 
 
−
public void onEvent(Event event) throws Exception {

2. Clone cell style<br/>
 
−
If we wanna to keep original cell style and only modify part of style, we can use the sample code below to clone a cell style.
 
−
<source lang="java" >
 
 
CellStyle cloneStyle(CellStyle srcStyle, Book book) {
 
CellStyle cloneStyle(CellStyle srcStyle, Book book) {
 
CellStyle newStyle =  book.createCellStyle();
 
CellStyle newStyle =  book.createCellStyle();

====Color====
−
We can get color from CellStyle.getFillForegroundColor(), it return a color index. However, we usually use color in #RRGGBB format. We can translate string to index by BookHelper.rgbToIndex(book, color)
+
We get color from <javadoc directory="zss" method="getFillForegroundColorColor()">org.zkoss.poi.ss.usermodel.CellStyle</javadoc>.  
  
−
After we clone cell style, we can modify color by CellStyle.setFillForegroundColor(), and use Range.setStyle() to set new style

Purpose

ZK Spreadsheet supports various cell style and font style.

Style Supported Notes
Font / Font Color / Fill Color Cause of browser limitation, font also depends on installed font on client side
Border / Border Color Cause of browser limitation, only solid/dashed/dotted border are supported now.
Alignment Horizontal, Vertical Alignment
Text Wrap & Overflow
Merged Cell Horizontal/Vertical Merged Cell
Data Formats Format cell

Clone Cell Style

To keep original cell style and only modify part of style, we can use the CellStyle.cloneStyleFrom(CellStyle) to clone a cell style. 

CellStyle cloneStyle(CellStyle srcStyle, Book book) {
	CellStyle newStyle =  book.createCellStyle();
	newStyle.cloneStyleFrom(srcStyle);
	return newStyle;
}

Cell Style

Color

We get color from CellStyle.getFillForegroundColorColor().

After we clone cell style, we can modify color by CellStyle.setFillForegroundColor(Short), and use Range.setStyle(CellStyle) to set new style 

public void setCellColor(String color) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
	final Color newColor = BookHelper.HTMLToColor(book, color);
		
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			CellStyle cellStyle = cell.getCellStyle();
			final Color srcColor = cellStyle.getFillForegroundColorColor();
				
			if (!Objects.equals(newColor, srcColor)) {
				CellStyle newStyle = cloneStyle(cellStyle, book);
				newStyle.cloneStyleFrom(cellStyle);
				BookHelper.setFillForegroundColor(newStyle, newColor);//use CellStyle.setFillForegroundColor
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Alignment

Horizontal alignment

We can get the cell's horizontal alignment information by CellStyle.getAlignment(), and use CellStyle.setAlignment(Short) to set horizontal alignment. 

public void setAlignment(short alignment) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {

			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			short srcAlign = cell.getCellStyle().getAlignment();
			if (srcAlign != alignment) {
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setAlignment(alignment);
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}
VerticalAlignment alignment

We can get the cell's vertical alignment information by CellStyle.getVerticalAlignment(), and use CellStyle.setVerticalAlignment(Short) to set vertical alignment. 

public void setVerticalAlignment(short alignment) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {

			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			short srcAlign = cell.getCellStyle().getVerticalAlignment();
			if (srcAlign != alignment) {
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setVerticalAlignment(alignment);
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Border

We can set the border by Range.setBorders(Short, BorderStyle, String) 

void setBorder(String border) {
	//Border color
	String color = "#000000";
	//Border style
	BorderStyle style = "none".equals(border) ? BorderStyle.NONE : BorderStyle.MEDIUM;
		
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	int lCol = rect.getLeft();
	int rCol = rect.getRight();
	int tRow = rect.getTop();
	int bRow = rect.getBottom();
	if ("bottom".equals(border)) {
		Ranges.range(sheet, tRow, lCol, bRow, rCol).
			setBorders(BookHelper.BORDER_EDGE_BOTTOM, style, color);
	} else if ("top".equals(border)) {
		Ranges.range(sheet, tRow, lCol, tRow, rCol).
			setBorders(BookHelper.BORDER_EDGE_TOP, style, color);
	} else if ("left".equals(border)) {
		Ranges.range(sheet, tRow, lCol, bRow, lCol).
			setBorders(BookHelper.BORDER_EDGE_LEFT, style, color);
	} else if ("right".equals(border)) {
		Ranges.range(sheet, tRow, rCol, bRow, rCol).
			setBorders(BookHelper.BORDER_EDGE_RIGHT, style, color);
	} else if ("none".equals(border)) {
		Ranges.range(sheet, tRow, lCol, bRow, rCol).
			setBorders(BookHelper.BORDER_FULL, style, color);
	} else if ("full".equals(border)) {
		Ranges.range(sheet, tRow, lCol, bRow, rCol).
			setBorders(BookHelper.BORDER_FULL, style, color);
	}
}

Font Style

From CellStyle.getFontIndex(), we get font index in the book, then we can get Font from Book.getFontAt() Book.getFontAt(String) We can get or create Font by BookHelper.getOrCreateFont(Book, Sort, Color, Short, String, Boolean, Boolean, Short, Byte)

Font family

void setFontFamily(String fontName) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			Font srcFont = book.getFontAt(cell.getCellStyle().getFontIndex());
					
			if (srcFont.getFontName() != fontName) {
				Font newFont = BookHelper.getOrCreateFont(book, 
srcFont.getBoldweight(), BookHelper.getFontColor(book, srcFont), 
Font.getFontHeight(), fontName, srcFont.getItalic(), srcFont.getStrikeout(), 
srcFont.getTypeOffset(), srcFont.getUnderline());
						
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setFont(newFont);	
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Font size

We can get the font height by using Font.getFontHeight() , however the font size is different from the font height. The font height in unit's of 1/20th of a point, so we can transform the font size to the font height by 

short getFontHeight(int fontSize) {
	return (short) (fontSize * 20);
}

After we get the font height to set, we can use BookHelper.getOrCreateFont(Book, Sort, Color, Short, String, Boolean, Boolean, Short, Byte). 

void setFontSize(short fontHeight) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
			Cell cell = Utils.getOrCreateCell(sheet, row, col);
		
			Font srcFont = book.getFontAt(cell.getCellStyle().getFontIndex());
			if (srcFont.getFontHeight() != fontHeight) {
				Font newFont = BookHelper.getOrCreateFont(book, srcFont.getBoldweight(), 
BookHelper.getFontColor(book, srcFont), fontHeight, srcFont.getFontName(), 
srcFont.getItalic(), srcFont.getStrikeout(), srcFont.getTypeOffset(), srcFont.getUnderline());
					
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setFont(newFont);	
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Bold

We can get the font bold weight by employing Font.getBoldweight() 

void setFontBold(boolean isBold) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			Font srcFont = book.getFontAt(
						cell.getCellStyle().getFontIndex());
					
			boolean srcBold = srcFont.getBoldweight() == Font.BOLDWEIGHT_BOLD; 
			if (srcBold != isBold) {
				Font newFont = BookHelper.getOrCreateFont(book, 
isBold ? Font.BOLDWEIGHT_BOLD : Font.BOLDWEIGHT_NORMAL, 
BookHelper.getFontColor(book, srcFont), srcFont.getFontHeight(), 
srcFont.getFontName(), srcFont.getItalic(), srcFont.getStrikeout(),
 srcFont.getTypeOffset(), srcFont.getUnderline());
						
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setFont(newFont);
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Italic

We can know whether the font uses italic or not by Font.getItalic() 

void setItalic(boolean isItalic) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			Font srcFont = book.getFontAt(
					cell.getCellStyle().getFontIndex());
					
			boolean srcItalic = srcFont.getItalic();
			if (srcItalic != isItalic) {
				Font newFont = BookHelper.getOrCreateFont(book, 
srcFont.getBoldweight(), BookHelper.getFontColor(book, srcFont), 
srcFont.getFontHeight(), srcFont.getFontName(), isItalic, 
srcFont.getStrikeout(), srcFont.getTypeOffset(), srcFont.getUnderline());
					
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setFont(newFont);
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Underline

We can get the font underline information by using Font.getUnderline() 

void setUnderline(boolean isUnderline){
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
		
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			Font srcFont = book.getFontAt(
					cell.getCellStyle().getFontIndex());
				
			boolean srcUnderline = srcFont.getUnderline() == Font.U_SINGLE;
			if (srcUnderline != isUnderline) {
				Font newFont = BookHelper.getOrCreateFont(book, srcFont.getBoldweight(), 
BookHelper.getFontColor(book, srcFont), srcFont.getFontHeight(), 
srcFont.getFontName(), srcFont.getItalic(), srcFont.getStrikeout(), 
srcFont.getTypeOffset(), isUnderline ? Font.U_SINGLE : Font.U_NONE);
						
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setFont(newFont);		
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Strikethrough

We can know whether the font uses strikethrough or not by Font.getStrikeout() 

void setStrikethrough(boolean isStrikethrough) {
	Rect rect = getSelection();
	Worksheet sheet = spreadsheet.getSelectedSheet();
	Book book = spreadsheet.getBook();
		
	for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
		for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
			Cell cell = Utils.getOrCreateCell(sheet, row, col);
			Font srcFont = book.getFontAt(
					cell.getCellStyle().getFontIndex());
					
			boolean srcStrikethrough = srcFont.getStrikeout();
			if (srcStrikethrough != isStrikethrough) {
				Font newFont = BookHelper.getOrCreateFont(book, srcFont.getBoldweight(), 
BookHelper.getFontColor(book, srcFont), srcFont.getFontHeight(), 
srcFont.getFontName(), srcFont.getItalic(), isStrikethrough, 
srcFont.getTypeOffset(), srcFont.getUnderline());
						
				CellStyle newStyle = cloneStyle(cell.getCellStyle(), book);
				newStyle.setFont(newFont);
				Ranges.range(sheet, row, col).setStyle(newStyle);
			}
		}
	}
}

Data Format

Get data format using CellStyle.getDataFormat() and set new data format using CellStyle.setDataFormat(format) 

	private void setCellFormat(String format) {
		Book book = spreadsheet.getBook();
		short dstFormat = book.createDataFormat().getFormat(format);
		
		Rect rect = getSelection();
		Worksheet sheet = spreadsheet.getSelectedSheet();
		for (int row = rect.getTop(); row <= rect.getBottom(); row++) {
			for (int col = rect.getLeft(); col <= rect.getRight(); col++) {
				Cell cell = Utils.getOrCreateCell(sheet, row, col);
				CellStyle srcCellStyle = cell.getCellStyle();
				short srcDataFormat = srcCellStyle.getDataFormat();
				
				if (srcDataFormat != dstFormat) {
					CellStyle newStyle = book.createCellStyle();
					newStyle.cloneStyleFrom(srcCellStyle);
					newStyle.setDataFormat(dstFormat);
					Ranges.range(sheet, row, col).setStyle(newStyle);
				}
			}
		}
	}
