If the cell is missing from the file and you want to generate blank cell then you can use the Row.getCell([int], Row.CREATE_NULL_AS_BLANK), which will give you blank cell. Alternatively, you can use the Cell.columnIndex value while iterating to check for jumping numbers. You also need to specify MissingCellPolicy for this to get it work.<br /><br />But, as I said, I don't if this is your requirement. Please share more details. javin paulhttps://www.blogger.com/profile/15028902221295732276noreply@blogger.com
