Title: Prevent NPE when an uninitialized table cell is rendered.

This simply protects against a null value from the caller. The getTableCellRendererComponet can call with a null value if there has never been an update to the cell in the table. Hopefully this is not a naïve fix, I could't determine if there was a bigger problem that was allowing the table cell to be uninitialized.
