No worries...
in your style.css do the following (it is easily undoable by backing out the little 'x's I mention)
line 776 put a little 'x' in front of border-bottom and margin (to make it unrecognizable so css skips it):
.entry-content table, .comment-content table {
border-bottom: 1px solid
#ddd;
margin: 0 0 1.625em;
width: 100%;
}
that margin statement above (and the border bit)
line 791 line 782 put a little 'x' in front of border-top and padding (to make it unrecognizable so css skips it):
.entry-content td, .comment-content td {
border-top: 1px solid
#ddd;
padding: 6px 10px 6px 0;
}
line 782 put a little 'x' in front of line-height (to make it unrecognizable so css skips it):
.entry-content th, .comment-content th {
color:
#666;
font-size: 10px;
font-weight: 500;
letter-spacing: 0.1em;
line-height: 2.6em;
text-transform: uppercase;
}
