Hi @Fenelein
I’m not sure whether this is the normal way that people use. However, when formatting emails, I use a online html editor to get the format as a HTML code. There, I have created tables just like what you need and I have adjusted the column sizes and stuff like that. The code automatically generates in the site. Then what I do is, after everything is done, I get the code and copy it to a text file and save it. In the send mail activity, for the body, I mention the text I have in the text file in HTML format. This is the best approach that I have tried out and it works perfect for me.
Below is the site I use,
Check the below sample code I created for a table with different column widths.
<table style="width: 370px; height: 143px;">
<tbody>
<tr>
<td style="width: 124.233px;">Column 1</td>
<td style="width: 150.317px;">Column 2</td>
<td style="width: 73.45px;">Column 3</td>
</tr>
<tr>
<td style="width: 124.233px;">Data</td>
<td style="width: 150.317px;">Data</td>
<td style="width: 73.45px;">1</td>
</tr>
<tr>
<td style="width: 124.233px;">D</td>
<td style="width: 150.317px;">D</td>
<td style="width: 73.45px;">2</td>
</tr>
<tr>
<td style="width: 124.233px;">D</td>
<td style="width: 150.317px;">D</td>
<td style="width: 73.45px;">3</td>
</tr>
<tr>
<td style="width: 124.233px;">D</td>
<td style="width: 150.317px;">D</td>
<td style="width: 73.45px;">4</td>
</tr>
</tbody>
</table>
