Try saving the table as a document in RTF format, closing, then reopening RTF document, deleting the table from the original document & copying the table from the RTF document back to the original document. That will repair some forms of table corruption. If you open the RTF document in WordPad and make a trivial edit (e.g. insert a space after the table), then save & close, that tends to eliminate a lot of Style data.
