我正在使用PHPExcel将Excel（xlsx）文件加载到我的html页面中。
我设法使用下面的表格添加了一个新表格，但不幸的是，我添加的每一行都会覆盖第一行。有没有一种方法可以刷新，这样我就不会覆盖以前添加的值？
这是我添加新行的表格：
<form action="" method="post" id="AddForm" name="AddForm">
<input type="text" id="company" name="company" value="Enter new name" />
<input type="submit" id="save" name="add" value="add"/>
</form>
下面是我用来加载/显示/添加新行的代码
<?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";
?>
我找到了解决方案：在循环中，需要在每次请求后保存文件：
$objWorksheet->setCellValueByColumnAndRow(0,$num_rows+1,$company_name);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('myExcelFile.xlsx');
echo date('H:i:s') . " Write to Excel2007 format'n";
