[SOLVED] Tables in posts convert to text...

Running 3.4.4 on WP 2.8.6

I have a number of postings that are created as tables, using the standard HTML code, and they display properly using the default zebra striping.

Here's the source code of a few rows:
<span id="more-325"></span></p>
<table>
<tr>
<td>1000001071</td>
<td>RADAR ASSIGNMENT</td>
<td>02/01/2010</td>
<td>05:23</td>
<td>LONGLEY RD / DRUMLIN HILL RD</td>
<td>131</td>
<td>Candow, Gordon A.</td>
<td></td>
</tr>
<tr>
<td>1000001070</td>
<td>RADAR ASSIGNMENT</td>
<td>02/01/2010</td>
<td>01:20</td>
<td>499 MAIN ST</td>
<td>131</td>
<td>Candow, Gordon A.</td>
<td></td>
</tr>
<tr>
<td>1000001069</td>
<td>BUILDING CHECK</td>
<td>02/01/2010</td>
<td>01 :08</td>
<td>703 CHICOPEE ROW</td>
<td>131</td>
<td>Candow, Gordon A.</td>
<td></td>
</tr>


However, after one of the posts has been viewed by itself or in a category page, the table is converted to a paragraph style format on display (this is a view of the generated source; the actual post is still retaining the correct table format:

<div class="post-bodycopy clearfix"><p>1000001075<br />
REGISTRATION/INSPECTION<br />

02/01/2010<br />
08:15<br />
BOSTON RD / SANDY POND RD<br />
127<br />
Breslin, Peter S.</p>
<p>1000001074<br />
MN COMPLAINT<br />
02/01/2010<br />
07:17<br />

6 BOSTON RD<br />
127<br />
Breslin, Peter S.</p>
<p>1000001073<br />
AREA CHECK<br />
02/01/2010<br />
06:29<br />
21 HAZEL RD<br />
129<br />

Any ideas on what's happening and how to ensure that the table format is retained?

Thanks much!
