空列A和B成功删除，但C和D未移动到A和B，只有D移动到A单元格中未显示的单元格C值

Question

这是我的代码

$ objPHPExcel = new PHPExcel（）; $ objPHPExcel-＆gt; setActiveSheetIndex（0） - ＆gt; setCellValue（'C1'，'Hello'） - ＆gt; setCellValue（'C2'，'world！'） - ＆gt; setCellValue（'C3'，'Hello'） - ＆gt; setCellValue（'D1'，'test'） - ＆gt; setCellValue（'D2'，'world！'） - ＆gt; setCellValue（'D3'，'Hello'）;

$ worksheet = $ objPHPExcel-＆gt; setActiveSheetIndex（0）; $ highestColumn = $ worksheet-＆gt; getHighestColumn（）; $ highestColumn = PHPExcel_Cell :: columnIndexFromString（$ highestColumn） - 1; $ highestRow = $ worksheet-＆gt; getHighestRow（）; for（$ column = $ highestColumn; $ column＆gt; = 0; - $ column）{     for（$ row = 1; $ row＆lt; = $ highestRow; ++ $ row）{         $ cell = $ worksheet-＆gt; getCellByColumnAndRow（$ column，$ row）; $ err = $ cell-＆gt; getValue（）;          if（！empty（$ err））{                打破;         } if（empty（$ err））{         $ objPHPExcel-＆GT; getActiveSheet（） - ＆GT; removeColumn（ 'A'）;
        $ objPHPExcel-＆GT; getActiveSheet（） - ＆GT; removeColumn（ 'B'）;
        }}

Answer 1

$objPHPExcel->getActiveSheet()
    ->removeColumn('D');

删除列D

$objPHPExcel->getActiveSheet()
    ->removeColumn('D', 3);

从列D开始删除3个连续列（即D - F）

但是你需要自己编写逻辑来识别列是否为空

修改

$objPHPExcel = new PHPExcel();

$data = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9],
];
$objPHPExcel->getActiveSheet()->fromArray($data);

$objPHPExcel->getActiveSheet()
    ->removeColumn('B');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('removeColumnTest.xlsx');

上述代码有效，并创建一个包含以下内容的电子表格：

   A  B
1  1  3
2  4  6
3  7  9

这是删除列的预期结果....已删除了列B，并且所有后续列（在此示例中仅为C）被洗牌，以便列C成为新列B.

如何检查空白列

$worksheet = $objPHPExcel->getActiveSheet();
$highestColumn = $worksheet->getHighestDataColumn();
$highestColumn = PHPExcel_Cell::columnIndexFromString($highestColumn) - 1;
$highestRow = $worksheet->getHighestDataRow();
// Check columns in reverse order if you want to delete empty columns
//   because the removeColumn() has less work to do if we're deleting backwards
for($column = $highestColumn; $column >= 0; --$column) {
    // Loop through the rows in the current column
    for ($row = 1; $row <= $highestRow; ++$row) {
        // check the cell in each row
        $cell = $worksheet->getCellByColumnAndRow($column,$row);
        if (!empty($cell->getValue())) {
            // Don't bother checking any more cells in this column if a cell isn't empty
            // Just move on to the previous column
            break;
        }
        // column is empty, so do whatever you want here.... e.g. delete or whatever
    }
}
