java - 如何使用 Java Apache POI 在 Excel 工作表中隐藏以下未使用的行？

Question

我正在使用数据库中的数据填充模板 Excel 工作表:

 for (Map<String, Object> resultRow : dbResults) {
        if ((currentRow = sheet.getRow(currentDataRow)) == null) {
            currentRow = sheet.createRow(currentDataRow);   // Creates a new row.
        }
        //currentRow.getRowStyle().setHidden(false);

        for (int i = 0; i < resultColumns; i++) {
            currentCell = currentRow.getCell(i, Row.CREATE_NULL_AS_BLANK);
            setCellValue(currentCell, resultRow.get(dbcolumnNames[i]));
        }
        currentDataRow += 1;
    }

// How to hide all empty/Un-used rows following currentDataRow ?

目标实现:

• I want that the Un-Used rows following the populated rows should be hidden ?
• All Populated rows must be visible.
• Eg: If 1st 100 data rows are filled, then rows following 101 and onward should be hidden.

请帮忙!!

Answer 1

Row r = sheet.getRow(indexRow);
if ( r!=null ) {
    r.setZeroHeight(true);
}
