I see that you make a fork of a lib and since you rewrite it and make improvements I have a question. Does your fork support grouping cells? Like: <table> <thead> <tr> <th>A</th> <th>B</th> <th>C</th> </tr> </thead> <tbody> <tr> <td rowspan="2">A1</td> <td>B1</td> <td>C1</td> </tr> <tr> <td>B2</td> <td>C2</td> </tr> <tr> <td rowspan="2">A3</td> <td colspan="2" align="center">B3</td> </tr> <tr> <td>B4</td> <td>C5</td> </tr> </tbody> </table>
