According to statistics, this is not your first post here. But anyway, welcome.

At the bottom I noticed you have a row with very large "colspan" - 29 in total but I fail to count that many at other rows. Are you sure that is correctly computed? If columns are not counted accurately your table-based layout may mess-up, and that is sort of expected

Oh by the way, you should specify 'px' explicitly in CSS style properties. Otherwise that is incorrect by standard and may be rejected by some browsers as invalid (that may cause the entire style declaration to be skipped if done the strict way).

I recommend you also enclose the attribute values in quotes in HTML. While for plain HTML it is not necessary, you should try to do this to move closer to XHTML, that by XML specification requires all attribute values enclosed.

I'm not on a Windows computer so I cannot confirm what your page looks like on IE. My recommendation is, first fix your HTML and CSS so that they are all valid first, then cater for cross-browser rendering issues. That way it would be easier to fix specific issues. IE in particular does not have great debugging support builtin, so it is particularly difficult to spot coding issues.
