On my journal, its a long series of tables, or journal entries. they're all centered but I want them to be aligned on the right as seen here (http://www.livejournal.com/~prechuzdime). thanx!

try adding:
align="right" to your tables' codes

well I tried it but it didn't work. Is there a some HTML code that I could put in to make all the tables aligned on the right w/ just one code?

align="right" didn't work?

<table border="1" align="right">
<tr>
<td>hi</td>
</tr>
<tr>
<td>Or hello</td>
</tr>
</table>

if you wanted one code to align them all, place <p align="right"> 4 ur tables, and </p> after them
