If you click on the "Setup" button you’re presented with a dialog box that allows you to modify some of the properties of your HTML document. 

(Figure 12.13)

If you select the "Auto-Naming" drop down menu you can choose to modify the naming convention that Fireworks uses.  By default it uses the document’s name or "basename" and follows that with the row number and column number of the individual graphics that are exported.  You can change this so the basename is followed by a letter or a number if you wish. Check your options by selecting the menu and choose the one that best suits your needs.

The "Table" drop down menu lets you choose the way that Fireworks lays your tables out.  If you choose Nested Tables you will end up with Tables with-in Tables if your content is somewhat complex.  This adds extra HTML code to your document, which isn’t a good idea.  If you choose the "Single Table" option you run the risk of having your content display improperly because Table pixel and width settings are notoriously unreliable when handled by a variety of different browsers.   For this reason you probably wouldn’t choose this option.  You can add a 1-pixel transparent shim to your table, which will make absolutely certain that, no matter what the users browser and display settings are, your page will display the way you intended it to.  Choose "1-pixel transparent shim".

Make sure the "Export Undefined Slices" checkbox is selected.  If it isn’t any content in your document that isn’t covered by a slice object will not be exported.

Selecting "Multiple Nav Bar HTML Pages" will export multiple HTML documents for use in documents without frames.
