PHPExcel为合并单元格设置AutoSize-php问题

PHPExcel setAutoSize for merged cells(PHPExcel为合并单元格设置AutoSize)

本文介绍了PHPExcel为合并单元格设置AutoSize的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

未合并的代码

$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();

$sheet->setCellValueByColumnAndRow(0, 1, 
        "test test test test test test test test");
$sheet->getColumnDimension('A')->setAutoSize(true);

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

合并代码

$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();

$sheet->setCellValueByColumnAndRow(0, 1, 
        "test test test test test test test test");
//this breaks the width calculation
$sheet->mergeCells('A1:B1');
$sheet->getColumnDimension('A')->setAutoSize(true);

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

据我所知，没有标准的方法来设置合并单元格的自动大小。是否有解决此问题的方法？

推荐答案

您可以在合并单元格之前使用->calculateColumnWidths()计算列宽，然后使用->setAutoSize(false)确保不会再次计算它们。代码可能会如下所示：

// Set the data in the cells
$objPHPExcel->getActiveSheet()->fromArray($sheet, null, 'A1');

// Calculate the column widths
foreach(range('A', 'E') as $columnID) {
    $objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(true);
}
$objPHPExcel->getActiveSheet()->calculateColumnWidths();

// Set setAutoSize(false) so that the widths are not recalculated
foreach(range('A', 'E') as $columnID) {
    $objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(false);
}

// Merge cells
$objPHPExcel->getActiveSheet()->mergeCells("A1:A5");
