how to fix/workaround a truncated table display

what I want to polish is a single table within the epub of Hilary Clinton - How I Lost. I jsut want to tweak my own reading copy.

The epub opens with a two column table called cast of characters, which looks ok in sigil, but on my tablet in moon+ the right hand column is truncating - missing some characters.-
[ A common issue with tables I believe and a reason to NOT use them.
BUt in this case, the publisher has, so I figured I'd try to learn enough about table CSS to see if I can tweak the display within my personal copy of it.

or use a quick and dirty way to just wipe all the table code & go to a simple text list, with some tab or alt separator , if that is easier?

I will also check out the kindle azw sample version, if there is one, to see if that has been coded differently/ works better on tablet.

so here's a small fair use bit - can anyone advise on how to tweak it so that all text is visible- it does seem to wrap, but only after some stuff within the right hand column table boxes is lost

my immediate prime suspects is columen of 25% and 50% that does not add up to 100% ?
<h1 class="chaptertitle">CAST OF CHARACTERS</h1>

<table cellpadding="0" cellspacing="0" class="table-note" width="100%">
<colgroup class="calibre3">
<col width="25%" class="calibre4"/>

<col width="60%" class="calibre4"/>
</colgroup>

<tbody>
<tr class="calibre5">
<td valign="top" class="calibre6">
<b class="calibre7">Huma Abedin</b>
</td>

<td valign="top" class="calibre6">
Hillary Clinton’s closest aide
</td>
</tr>

<tr class="calibre5">
<td valign="top" class="calibre6">
<b class="calibre7">Julian Assange</b>
</td>

<td valign="top" class="calibre6">
Founder and publisher of WikiLeaks
</td>
</tr>
...
heres a bit that truncates as its too wide:
<td valign="top" class="calibre6">
Secretary of state in the George H.W. Bush administration
</td>

and some related css. ( I ran it through a calibre conversion so see if that would auto fic it - hence all the calibre CSS styles - but no joy)
