An enhancement suggestion if it has not already been requested.  If the row display would optionally allow for alternating colors (2), this would increase readability on large tables immensely.   Allow the developer to select the colors through two new settings not changing the default color already set but adding two new color options for the rows.  In effect you would have a background color as currently available (this would differentiate the table headings) and the two additional colors for the alternating row display.  Thanks for your consideration, you all are doing a fantastic job and as I become more familiar with the product I hope to be able to contribute more than just by requesting changes.  

By the way, the fix for this has got to be the simplest of the most frequent requests. It's essentially a two-line fix. First, open the UserDefinedTable.ascx file and add AlternatingItemStyle-CssClass="NormalAlternate" to the grdData data grid control. Next, add the NormalAlternate CSS class in any CSS file with whatever properties you want. In hopes of getting this integrated into the core, I just added the CSS class to the Portals/_default/default.css file (and a stub in the Portals/_default/portal.css template).

Obviously, you can choose a different name for the CSS class. The rows all use the Normal CSS class right now, so that's why I chose NormalAlternate. I started to create another table management setting, but figured most people would be fine with having this setting across the board for all UDT module instances. If that's not the case, let me know and I can try to add it to the management page.

Not that it's hard, but this is what I put for the style...
.NormalAlternate { background-color : #eeeeee; }
