OooBasic 找出 sheet 的使用範圍

　
sub usedArea

　oDoc = thisComponent
　oPlan = oDoc.getSheets().getByIndex(1) '指定是那張 sheet
　oCursor = oPlan.createCursor()
　oCursor.gotoStartOfUsedArea(False)
　oCursor.gotoEndOfUsedArea(True)
　aAdd = oCursor.getRangeAddress()
　print "StartRow=" & aAdd.StartRow+1; ", StartColumn=" & aAdd.StartColumn+1; ", EndRow=" & aAdd.EndRow+1; ", EndColumn" & aAdd.EndColumn+1

end sub
