使用PHPExcel添加新行？

Question

如何使用PHPExcel向现有的.xls文件添加新行？

我是否必须计算已存在的行数？

如果是这样,我如何为excel文件执行此操作？

Answer 1

假设这个设置:

$objPHPExcel = PHPExcel_IOFactory::load("foo.xlsx");
$objWorksheet = $objPHPExcel->getActiveSheet();

您可以像这样获取行数:

$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);

这之前增加了1个新行$num_rows.

Answer 2

上面的示例仅添加一个空行.以下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";
        ?>
