Dear Mehtaz,
it seems that my question was not clear enough, so I will try to make it a bit clearer.
It's about the column width in a table, which I inserted in SP Page Builder using the table add-on in a column add-on. Unfortunately, the first column does not adapt to the text. And the other columns (unfortunately) need the custom CSS I showed in my request to nicely adapt theier width to the contained text.
In your custom CSS you refer to the form builder add-on, which my difficulty has nothing to do with. Looking at the generated source code for the table in my page, I would rather expect CSS for the sppb-addon-table.
Here another screenshot that should help you find the table on my website:

The red arrow points to the table in question which is located at the bottom of the page in the "Kontakt" section.
When I create a table in pure HTML, the column widths adapt by default to the text they contain. The HTML looks like this:
<tr>
<td>Telefon</td><td>:</td><td>044 123 45 67</td>
</tr>
<tr>
<td>Telefax</td><td>:</td><td>044 123 45 68</td>
</tr>
The result gets rendered in the browser like this (which is what I want):

So I suspect that the SPPB is overriding formatting for tables. And it's quite possible that I just haven't found the right parameter in the settings for the table add-on. That's why I made my support request with the hope that someone from your support team can show me the necessary setting (probably even without custom CSS).
To add: the table add-on has a lot of settings, so I guess that my problem can be solved via one of them.
Regards, Ernst
