How to styling the cell in PHPexcel? - php

Question

I would like to:
1) set min-width of the cell
On the internet there is some discussion about this , but I find the code not work:
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(100);
the column size is not expand according to the data size / preset width
2) underline the cell
I am making an account table, so I would like to underline some row
$styleArray = array(
'borders' => array(
'bottom' => array(
'style' => PHPExcel_Style_Border::BORDER_THIN
)
)
);
$sheet->getStyle('A1')->applyFromArray($styleArray);
However the underline is not exist, I wonder is it due to the border also count as 1 line? for example , if A1 is underlined, then I need to user A3 for the next row.
Thanks a lot for helping.
Update:
1) set min-width:
From the source code the column is a number instead of string , so I try like this but still no luck
$excel->getActiveSheet()->getColumnDimensionByColumn(0)->setAutoSize(false);
$excel->getActiveSheet()->getColumnDimensionByColumn(0)->setWidth('4.42');
2) underline is working now
$border_bottom = array(
'borders' => array(
'bottom' => array(
'style' => PHPExcel_Style_Border::BORDER_THIN
)
)
);
$excel->getActiveSheet()->getStyle("7")->applyFromArray($border_bottom);
it works, but just wondering can I underline when set cell instead of hardcode the position: A1:B2 etc...

In number 1, you can check this: PHPExcel auto size column width
With regards on your number 2, have you tried to use this? Instead of underlining the cell, you underline the value of the cell.
$styleArray = array(
'font' => array(
'underline' => PHPExcel_Style_Font::UNDERLINE_SINGLE
)
);
$objPHPExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);
unset($styleArray);
If you want a range of cells to be underlined, instead of:
objPHPExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);
use:
$objPHPExcel->getActiveSheet()->getStyle('A1:A3')->applyFromArray($styleArray);
