Question

in a simple HTML table I would like to remove the last column

<table>
<tbody>
<tr>
    <th>1</th>
    <th>2</th>
    <th>3</th>
    <th rowspan="3">I want to remove this</th>
</tr>

<tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td rowspan="3">I want to remove this</td>
</tr>

I am using this code, but I am still left with the content and the th and td rowspan

$myTable = preg_replace('#</?td rowspan[^>]*>#i', '', $myTable);
echo $myTable

Question: how do I remove the last column and it’s content ?

Answer 1

I guess this will do it

preg_replace("/<(?:td|th)[^>]*>.*?<\/(?:td|th)>\s+<\/tr>/i", "</tr>", $myTable);

assuming you have closing tr tag (</tr>) at the end of each row unlike in your example

Edit: this will remove any <td> or <th> elements before closing </tr> no matter if they have any attributes

working example
