Hi all：

in my site, some important posts will use table, and need use colspan and rowspan , but i find these tags can’t be set, so it will be ignore.

```
<table border="1">
<tr>
  <th colspan="2">number</th>
</tr>
<tr>
  <td>555 77 854</td>
  <td>555 77 855</td>
</tr>
</table>

```

**just show like this:** ( colspan=“2” will be ignore)

| number |
| --- |
| 555 77 854 | 555 77 855 |

now how i can add these support?

Table support is not currently built in with markdown. There are some changes to be made to be made to markdown in a future release nut no guarantee when.

Check this topic
