Hi there, I suppose in-post styling is not working with wpforo, am I right? I mean in the source code section, I include some additional css just for the post but it just disappears. I also tried html stying but this does now work aswell. Example codes that I used;

<table><tr><th colspan="2">Vegetables</th></tr>
<tr><td>Potato</td><td>Tomato</td></tr>
</table>

<style>
table, tr, th { border: 2px solid #000;}
</style>

And neither;

<table border="1"> 

working. Or shall I use custom css in wordpress in every case?

Update: Alright I found workaround. Assigned id to tables and styled them in custom css. 

This is how you gonna do incase you wonder;

<table id="example">

This way you assign an id to your table, then style them in wordpress' custom css;

#example table, th, tr, td { insert some css here and add !important }
