How to "lock" (fix?) Leftmost Column

I'm using D7, iPhone scroll region, and in that I've got a TTIWDBAdvWebGrid.  My data is connected and I'm starting to understand how to use the grid.  One thing I can't figure out is, on the tiny iPhone screen, it is important that I be able to programmatically lock the leftmost column so that it doesn't scroll out of veiew when the user scrolls the columns.   I have been reading here in the forum and on the string grid there is a FixedLeftCols or some such, but there is no equivalent property for the TTIWDBAdvWebGrid that I can find.  Where is it?  How do I accomplish this?

Thanks in advance for any help you can provide.

Sorry, unfortunately, at this time such feature is not built-in.
