Question

在我的应用程序中，我需要以预定义的格式导出到xls文件。

所以我只是整合了php_excel2007。我正在使用一个预定义格式的模板。

问题这里的细胞数据可能会动态变化。如果数据远大于单元格高度，那么数据就会崩溃。

无论如何，根据细胞的含量增加细胞的高度（在XLX而不是xlsx中）？

Answer 1

唯一的方法是this answer中有关此主题的上一个问题：将行高设置为自动调整，以及要包装的单元格对齐。无论您使用Excel5 Writer还是Excel2007 Writer，这都应该以相同的方式工作。

$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');

在代码示例中添加了注释，以解释每个被调用方法实际执行的操作

setRowHeight为-1表示自动高度（基于单元格数据）

// auto-size on row 1

$objWorksheet->getRowDimension('1')->setRowHeight(-1);
