Cannot set culumn width

[pippuccio76]

HI , i try to set culumn width , this is my code :

` $mySpreadsheet = new Spreadsheet();

    //se presente cancello l'excel 
    if(is_file((WRITEPATH . 'output.xlsx'))){

        unlink((WRITEPATH . 'output.xlsx'));
    }


    // delete the default active sheet
    $mySpreadsheet->removeSheetByIndex(0);

    // Create "Sheet 1" tab as the first worksheet.
    // https://phpspreadsheet.readthedocs.io/en/latest/topics/worksheets/adding-a-new-worksheet
    $worksheet1 = new Worksheet($mySpreadsheet, "Foglio 1");
    $mySpreadsheet->addSheet($worksheet1, 0);
    $mySpreadsheet->setActiveSheetIndexByName("Foglio 1");
    /*
    // Create "Sheet 2" tab as the second worksheet.
    $worksheet2 = new Worksheet($mySpreadsheet, "Sheet 2");
    $mySpreadsheet->addSheet($worksheet2, 1);
    */


    
    //imposto la larghezza delle colonne
    $worksheet1->getColumnDimension('A')->setAutoSize(false));
    $worksheet1->getColumnDimension('B')->setAutoSize(false);
    $worksheet1->getColumnDimension('C')->setAutoSize(false);
    $worksheet1->getColumnDimension('D')->setAutoSize(false);
    $worksheet1->getColumnDimension('E')->setAutoSize(false);
    $worksheet1->getColumnDimension('F')->setAutoSize(false);
    $worksheet1->getColumnDimension('G')->setAutoSize(false);
    $worksheet1->getColumnDimension('H')->setAutoSize(false);
    
    $worksheet1->getColumnDimension('A')->setWidth(15);
    $worksheet1->getColumnDimension('B')->setWidth('20');
    $worksheet1->getColumnDimension('C')->setWidth('20');
    $worksheet1->getColumnDimension('D')->setWidth('12.57');
    $worksheet1->getColumnDimension('E')->setWidth('6.57');
    $worksheet1->getColumnDimension('F')->setWidth('8.71');
    $worksheet1->getColumnDimension('G')->setWidth('9');
    $worksheet1->getColumnDimension('H')->setWidth('9');


    //imposto la riga 2
    $worksheet1->getRowDimension('1')->setRowHeight(12.75);
    $worksheet1->getRowDimension('2')->setRowHeight(102);
    $worksheet1->getRowDimension('3')->setRowHeight(12.75);
    $worksheet1->getRowDimension('4')->setRowHeight(15);
    $worksheet1->getRowDimension('5')->setRowHeight(15);

    for ($i=6; $i <=15 ; $i++) {

        $worksheet1->getRowDimension($i)->setRowHeight(12.75);

    }

    $worksheet1->getRowDimension('16')->setRowHeight(17.25);
    $worksheet1->getRowDimension('17')->setRowHeight(38.25);

    for ($i = 18; $i <= 55; $i++) {

        $worksheet1->getRowDimension($i)->setRowHeight(12.75);
    }
    
    //unisco le celle 
    $worksheet1->mergeCells('A2:H2');

    $mySpreadsheet->getDefaultStyle()->getFont()->setName('Arial');
    $mySpreadsheet->getDefaultStyle()->getFont()->setSize(20);
    $mySpreadsheet->getDefaultStyle()->getFont()->setBold(true);


    $worksheet1->getStyle('A2:H60')->getAlignment()->setHorizontal(Alignment::HORIZONTAL_CENTER);
    $worksheet1->getStyle('A2:H60')->getAlignment()->setVertical(Alignment::VERTICAL_CENTER);
    $worksheet1->getStyle('A2:H60')->getAlignment()->setWrapText(true);;

    $worksheet1->setCellValue('A2', "xxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxx");

    $worksheet1->mergeCells('E3:F3');
    $worksheet1->mergeCells('G3:H3');

    //IMPOSTO I BORDI

    $styleArray = [
        'borders' => [
            'allBorders' => [
                'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THICK,
                'color' => ['argb' => '0a0a0a'],
            ],
        ],
    ];

    $worksheet1->getStyle('A3:H3')->applyFromArray($styleArray);

    $worksheet1->getStyle('A3:H3')->getFont()->setName('Arial');
    $worksheet1->getStyle('A3:H3')->getFont()->setSize(10);
    $worksheet1->getStyle('A3:H3')->getFont()->setBold(true);

    $worksheet1->setCellValue('A3', "CLIENTE");
    $worksheet1->setCellValue('B3', "FATT");
    $worksheet1->setCellValue('D3', "DDT");
    $worksheet1->setCellValue('E3', "DATA");
    $worksheet1->setCellValue('E3', "PREAVVISO N°");
    

    // sheet 1 contains the birthdays of famous people.
    /*
    $sheet1Data = [
        ["First Name", "Last Name", "Date of Birth"],
        ['Britney',  "Spears", "02-12-1981"],
        ['Michael',  "Jackson", "29-08-1958"],
        ['Christina',  "Aguilera", "18-12-1980"],

    ];

    $worksheet1->fromArray($sheet1Data);
        */

    // Change the widths of the columns to be appropriately large for the content in them.
    // https://stackoverflow.com/questions/62203260/php-spreadsheet-cant-find-the-function-to-auto-size-column-width
    $worksheets = [$worksheet1];



    // Save to file.
    $writer = new Xlsx($mySpreadsheet);
    $writer->save(WRITEPATH.'output.xlsx');

`

But if i see the culum width f.e. for culumn A hi have this :

instead of 15 .

the version is 2.0.1

You can set the column width, and, if you look at the xml for the spreadsheet, you'll see that all the columns have the width you've specified. The problem is that Excel then manipulates the value so that you see a different value in the Excel UI.

<cols>
<col min="1" max="1" width="15" customWidth="true" style="0"/>
<col min="2" max="2" width="20" customWidth="true" style="0"/>
<col min="3" max="3" width="20" customWidth="true" style="0"/>
<col min="4" max="4" width="12.57" customWidth="true" style="0"/>
<col min="5" max="5" width="6.57" customWidth="true" style="0"/>
<col min="6" max="6" width="8.71" customWidth="true" style="0"/>
<col min="7" max="7" width="9" customWidth="true" style="0"/>
<col min="8" max="8" width="9" customWidth="true" style="0"/>
</cols>

You can see this behavior in Excel without involving PhpSpreadsheet. Open a spreadsheet, set a cell, change its column width, save the spreadsheet. The value in the UI will not match the value in the xml.

What the "width" represents is (taken from http://web.mit.edu/~stevenj/www/ECMA-376-new-merged.pdf):

Column width measured as the number of characters of the maximum digit width of the
numbers 0, 1, 2, ..., 9 as rendered in the normal style's font. There are 4 pixels of margin
padding (two on each side), plus 1 pixel padding for the gridlines.

If you take a look at your spreadsheet, and fill in, say, cell A4, you'll see that you can fit exactly 15 zero characters in it; in B4, you can fit exactly 20 zero characters, in G4, 9 characters, etc. This matches the integer widths you specified. In cell F4, you can fit 8 zero characters, but not 9; this accords with the width of 8.71 that you specified.
