This is obviously not necessary for your situation, but MIF mucking for tables is sometimes done. We use it to convert arbitrary (pasted-in) spreadsheet data to a fully formatted FM table with useful cross-reference markers already in place. Paste in the data in one sheet. Copy out the raw MIF from another. Open in FM and copy to final document. The spreadsheet was originally created by deconstructing a formatted table in MIF.
