Purpose

ZK Spreadsheet can use Range.delete(Integer) to delete range, rows or columns.

ZUML

<zk>
<div height="100%" width="100%" apply="demo.DeleteRangeComposer">
	<div height="3px"></div>
	<menupopup id="cellMenupopup">
		<menuitem id="shiftCellLeft" label="Shift cells left"></menuitem>
		<menuitem id="shiftCellUp" label="Shift cells up"/>
		<menuitem id="deleteEntireRow" label="Entire row" />
		<menuitem id="deleteEntireColumn" label="Entire column" />
	</menupopup>
	<spreadsheet id="spreadsheet" src="/demo_sample.xls"	
			maxrows="200" 
			maxcolumns="40"
			width="100%"
			height="450px"></spreadsheet>
</div>
</zk>

Composer

Open Menu

We can use onCellRightClick to get the current mouse position and open popup. 

int rowIndex;
int colIndex;
Worksheet currentSheet;
Spreadsheet spreadsheet;
Menupopup cellMenupopup;
public void onCellRightClick$spreadsheet(CellMouseEvent event) {
	rowIndex = event.getRow();
	colIndex = event.getColumn();
	currentSheet = event.getSheet();
	cellMenupopup.open(event.getPageX(), event.getPageY());
}

Shift Cells Left

public void onClick$shiftCellLeft() {
	Range rng = Ranges.range(currentSheet, rowIndex, colIndex);
	rng.delete(Range.SHIFT_LEFT);
}

Shift Cells Up

public void onClick$shiftCellUp() {
	final Range rng = Ranges.range(currentSheet, rowIndex, colIndex);
	rng.delete(Range.SHIFT_UP);
}

Delete Entire Row

public void onClick$deleteEntireRow() {
	Row row = currentSheet.getRow(rowIndex);
	int lCol = row.getFirstCellNum();
	int rCol  = row.getLastCellNum();
	Ranges.range(currentSheet, rowIndex, lCol, rowIndex, rCol).delete(Range.SHIFT_UP);
}

Delete Entire Column

public void onClick$deleteEntireColumn() {
	int tRow = currentSheet.getFirstRowNum();
	int bRow = currentSheet.getPhysicalNumberOfRows();
	Ranges.range(currentSheet, tRow, colIndex, bRow, colIndex).delete(Range.SHIFT_LEFT);
}
