How to create TCPDF HTML table with variable row paddings

Question

I'm trying to create an HTML table in TCPDF, with few rows having grater space between rows (padding), and others having smaller padding.

$html = '<table border="0" cellpadding="6">
        <tr>
            <td style="width="52%">' . lang('ticket_name') . '</td>
            <td style="width="18%">' . lang('ticket_price') . '</td>
            <td style="width="12%">' . lang('quantity') . '</td>
            <td style="width="18%">' . lang('total') . '</td>
        </tr>
    <tr>
            <td style="padding: 10px">' . $item['name'] . '</td>
            <td style="padding: 10px">' . $item['unit_price'] . '</td>
            <td style="padding: 10px">' . $item['quantity'] . '</td>
            <td style="padding: 10px">' . $item['row_total'] . '</td>
        </tr>
        <tr>
            <td style="text-align:right" colspan="3">' . lang('price_basis') . ': </td>
            <td>' . $totals['total_before_tax'] . '</td>
        </tr>
            <tr>
            <td style="text-align:right" colspan="3">' . 'Ukupni popust' . ': </td>
            <td>' . $totals['total_discount'] . '</td>
        </tr>
            <tr>
            <td style="text-align:right" colspan="3">' . 'Sveukupno' . ': </td>
            <td>' . $totals['grand_total'] . '</td>
        </tr>
    </table>';
$pdf->writeHTML($html, $linebreak = true, $fill = false, $reseth = true, $cell = false, $align = '');

As you can see, I have a cellpadding attribute in the table tag, which is working fine, but I want to have a different padding in the second row. Padding style obviously isn't working on 'td' nor on 'tr' tags.

I know it can be done with two separate tables with different cellpaddings, but it seems pretty wrong. There must be another way.

Answer 1

TCPDF doesn't support all CSS attributes, for example TCPDF doesn't support padding and margin attributes. You can simulate paddings by inner table:

<tr>
 <td>
  <table><tr>
   <td style="width:10px;"></td>
   <td>' . $item['name'] . '</td>
   <td style="width:10px;"></td>
  </tr></table>
 </td>
</tr>

Or you can use different tables with different cellpadding for each row:

<table border="0" cellpadding="6">
 <tr>
  <td>' . lang('ticket_name') . '</td>
  <td>' . lang('ticket_price') . '</td>
  <td>' . lang('quantity') . '</td>
  <td>' . lang('total') . '</td>
 </tr>
</table>
<table border="0" cellpadding="5">
 <tr>
  <td>' . $item['name'] . '</td>
  <td>' . $item['unit_price'] . '</td>
  <td>' . $item['quantity'] . '</td>
  <td>' . $item['row_total'] . '</td>
 </tr>
</table>
