I've installed Save Composite Custom Columns, and customized it to run. I've closed Calibre and restarted it. When I look at the Calibre database, I see it has a table books_plugin_data, but this table has no values. Is there something additional I need to do to get it to populate the column?

When calibre starts or opens another library a memory resident database is built that includes the 'calculation' of composite columns using the specified templates. The memory resident database is used for search, sorting etc and by plugins.
The Save Composite Columns plugin was a bum steer. As chaley explained it doesn't store the composite column values as regular custom columns, afaik it's only used by Calibre Companion which chaley wrote.
I suggest you take up why MCS doesn't allow composite date columns with a post in the MCS thread, include a reference to this one as background. The author, DaltonST, is normally very responsive to issues such as this.
