In FrontPage, create a new page.
Open Windows Explorer and resize FrontPage so that both can be seen on
screen at the same time.
In Windows Explorer, browse to the Word Document. Don not open the
document.
Drag the document onto the open page.
The table will be placed on the page using clean HTML. There may be a
little editing to do (in my test I lost different coloured cell borders),
the amount of editing will depend on the complexity of the table content,
but the result is a perfectly usable table with none of the usual Word
bloat.
