php_excel07-如何根据单元格数据增加单元格的高度(xls)

Question

在我的应用程序中，我需要以预定义格式导出到 xls 文件。

所以我刚刚集成了 php_excel2007。我正在使用一个具有预定义格式的模板。

问题 这里的单元格数据可能会动态变化。如果数据远大于单元格高度，则数据正在崩溃。

那么是否可以根据单元格的内容(在 XLX 中而不是 xlsx 中)增加单元格的高度？

唯一的方法如 this answer 中所述对于您之前关于此主题的问题:将行高设置为自动调整，并将单元格对齐方式设置为换行。这应该以相同的方式工作，无论您使用 Excel5 Writer 还是 Excel2007 Writer。

$objPHPExcel = new PHPExcel();

// Set some long string values in some cells
$objPHPExcel->getActiveSheet()->getCell('A1')->setValue("This is a large block of text,\ncomprising several lines,\nthat will be set to autofit.");
$objPHPExcel->getActiveSheet()->getCell('A2')->setValue("This is a large block of text that will NOT be set to autofit.");
$objPHPExcel->getActiveSheet()->getCell('B1')->setValue("This is another large block of text without any line breaks, that will be set to autofit.");
$objPHPExcel->getActiveSheet()->getCell('A3')->setValue("This is another large block of text,\ncomprising several lines,\nthat will be set to autofit.");
$objPHPExcel->getActiveSheet()->getCell('A4')->setValue("This is another large block of text without any line breaks, that will be set to autofit but not wrap.");
// Fix the column width to a reasonable size
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(30);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(30);
//  Set text wrap for cells A1 and B1. This forces the text to wrap, but doesn't adjust the height of the row
$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setWrapText(true);
$objPHPExcel->getActiveSheet()->getStyle('B1')->getAlignment()->setWrapText(true);
// Set rows 1, 3 and 4 to autofit the height to the size of text
$objPHPExcel->getActiveSheet()->getRowDimension(1)->setRowHeight(-1);
$objPHPExcel->getActiveSheet()->getRowDimension(3)->setRowHeight(-1);
$objPHPExcel->getActiveSheet()->getRowDimension(4)->setRowHeight(-1);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('testAutoHeight.xls');
