To help answer another user's question I discovered (sort of) a bug when trying to post HTML tables in a post.
EXAMPLE:
<TABLE align=center border=3 cellpadding=5 cellspacing=2>
<TR>
<TD>first column</TD>
<TD>second column</TD>
</TR>
<TR>
<TH colspan="2" align=center bgcolor="#999999"><font color="#eeeeee">second row colspan</font></TH>
</TR>
<TR>
<TD colspan=2><TABLE border=5><TR><TD>nested table</TD></TR></TABLE></TD></TR>
</TABLE>
When typing HTML formatted like this, Threads is adding line breaks to it, which breaks what was intended:
<table align="center" border="3" cellpadding="5" cellspacing="2"><br> <tbody><tr><br> <td>first column</td><br> <td>second column</td><br> </tr><br> <tr><br> <th colspan="2" align="center" bgcolor="#999999"><font color="#eeeeee">second row colspan</font></th><br> </tr><br> <tr><br> <td colspan="2"><table border="5"><tbody><tr><td>nested table</td></tr></tbody></table></td><br></tr></tbody></table>
Here are what's intended, and what's produced (below). All that caused by <BR>'s. Apparently you need to not format your HTML for it to display correctly:
