如何使用 PHPExcel 向现有的 .xls 文件添加新行?
我是否必须计算已经存在的行数?
如果是这样,我该如何为excel文件做到这一点?
假设这个设置:
$objPHPExcel = PHPExcel_IOFactory::load("foo.xlsx");
$objWorksheet = $objPHPExcel->getActiveSheet();
您可以像这样获得行数:
$num_rows = $objPHPExcel->getActiveSheet()->getHighestRow();
在此之后,您可以使用以下语句查看插入行:
$objWorksheet->insertNewRowBefore($num_rows + 1, 1);
这在之前添加了 1 个新行$num_rows
。
上面的示例只添加了一个空白行。下面的示例添加来自表单的数据。
<?php
require_once '../inc/phpexcel/Classes/PHPExcel.php';
require_once '../inc/phpexcel/Classes/PHPExcel/IOFactory.php';
$objPHPExcel = PHPExcel_IOFactory::load("myExcelFile.xlsx");
$objWorksheet = $objPHPExcel->getActiveSheet();
//add the new row
$num_rows = $objPHPExcel->getActiveSheet()->getHighestRow();
$objWorksheet->insertNewRowBefore($num_rows + 1, 1);
$name = isset($_POST['name']) ? $_POST['name'] : '';
if($submit){
//SAVING THE NEW ROW - on the last position in the table
$objWorksheet->setCellValueByColumnAndRow(0,$num_rows+1,$name);
}
//display the table
echo '<table>'."\n";
echo '<thead>
<tr>
<th>Company Name</th>
</tr>
</thead>'."\n";
echo '<tbody>'."\n";
foreach ($objWorksheet->getRowIterator() as $row) {
echo '<tr>'."\n";
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false);
foreach ($cellIterator as $cell) {
echo '<td>'.$cell->getValue().'</td>'."\n";
}
echo '</tr>'."\n";
}
echo '</tbody>'."\n";
echo '</table>'."\n";
?>
