php_excel07- How to make grow the height of cell based on cell data(xls)

问题

In my application i need to export to xls file in a predefined format.

so I just integrated php_excel2007. I am using one template with a predefined format.

The problem here is the cell data may change dynamically. if data is much bigger than cell height then data is collapsing.

So is ther anyway to increase the height of cell based on content of the cell(in XLX not xlsx)?

回答1:

The only way is as described in this answer to your previous question on this topic: setting the row height to autofit, and the cell alignment to wrap. This should work the same way, whether you use the Excel5 Writer or the 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');

EDIT

Added comments to the code sample to explain what each called method actually does

回答2:

setRowHeight to -1 for make auto height (based on cell data)

// auto-size on row 1

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