Open menu

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

int rowIndex;
int colIndex;
Sheet 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);
}
