TCPDF - Stroke thickness will not applied

[Collie-IT]

This is:

• [x] a bug report
• [ ] a feature request
• [ ] not a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

If I use a borderstyle like \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_HAIR In the PDF the line should be the size of the borderstyle in case aboth small.

What is the current behavior?

The lines get the same thickness because in protected function getCSSBorderStyle($cssborder) of <path>/vendor/tecnickcom/tcpdf/tcpdf.php the Parameter count will be interpreted like

    $bprop = preg_split('/[\s]+/', trim($cssborder));
        $border = array(); // value to be returned
        switch (count($bprop)) {
            case 3: {
                $width = $bprop[0];
                $style = $bprop[1];
                $color = $bprop[2];
                break;
            }
            case 2: {
                $width = 'medium';
                $style = $bprop[0];
                $color = $bprop[1];
                break;
            }
            case 1: {
                $width = 'medium';
                $style = $bprop[0];
                $color = 'black';
                break;
            }
            default: {
                $width = 'medium';
                $style = 'solid';
                $color = 'black';
                break;
            }
        }

PHP spreedsheet sends 4 parameters ("X X X !important") and all goes to the default: case.

What are the steps to reproduce?

Please provide a Minimal, Complete, and Verifiable example of code that exhibits the issue without relying on an external Excel file or a web server:

<?php

require __DIR__ . '/vendor/autoload.php';

// Create new Spreadsheet object
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

// add code that show the issue here...
$sheet = $spreadsheet->getActiveSheet();
$sheet->getStyle("A1")->getBorders()->getTop()->setBorderStyle(\PhpOffice\PhpSpreadsheet\Style\Border::BORDER_HAIR);
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Tcpdf');
$writer->save($tpath);

Which versions of PhpSpreadsheet and PHP are affected?

Tested with 1.8.2, 19.0

The dirty hotfix is to set a fall trough at getCSSBorderStyle($cssborder)of <path>/vendor/tecnickcom/tcpdf/tcpdf.php

switch (count($bprop)) {
            case 4: //fall trough for "'!important'"
            case 3: {
                $width = $bprop[0];
                $style = $bprop[1];
                $color = $bprop[2];
                break;
            }
