I used what you wrote me and it worked. Is the problem the colspan attribute or the th tag? The replacement has the colspan and it replaces th with td.
I did some testing and I found out after I push publish the th and the thead tags vanish. The original code was:
<th colspan="12">Winston-Salem Dash</th><br />
when I hit publish this becomes:
Winston-Salem Dash<br />
if I copy/paste your code in place of the plain text it works. I, also, found out that just changing th to td and leaving everything else as it is works fine:
<td colspan="12">Winston-Salem Dash</td><br />
Did WP develop an allergy to th? Should I alert someone? Any idea if WP will restore th tags? Or is this a feature and not a bug?
PS. I see now this:
The text in a th element is bold and centered.
The text in a td element is regular and left-aligned.
now I understand why you gave center and bold instructions in your code. If you don't text won't get centered, nor bolded since the th tag was replaced with a td tag
Thanks for the help.
