In addition, the FONT tag does not apply to the TABLE tag. In CSS it can, but not in HTML. It should be between each individual cell tags (TD and /TD or TH and /TH). And, better yet, between the P and /P tags within each cell.
Like the previous poster said though, it's much easier to apply some style one time to a style sheet than it is to search for and find hundreds of FONT tags in a table.
In the style sheet, you might have one font for the BODY (ie: body {font-size: 12px;} ), then one font size for a table (ie: table {font-size: 10px;} )
You might even play with creating a table CLASS so that only some tables get that size of font in them (ie: table.mine {font-size: 18pt;} ) and then in the TABLE tag itself, you type class="mine"
