Match source document's column widths
If this option is checked, the width of each column in the HTML document will be identical to that of the original document. If you select this option, remember that you cannot anticipate the font that will be used by the various browsers that display your document. Table data that fits snugly in your document may not fit well when displayed in a table of the same width but with a different font. It is best to let the browser adjust the column width to accommodate the text displayed.
