RFR: 8321970: New table columns don't appear when using fixed cell size unless refreshing tableView

Mon Dec 18 12:14:58 UTC 2023

This PR fixes an issue when a new `TableColumn` is added to a `TableView` control with fixed cell size set, where the `TableRowSkinBase` failed to add the cells for the new column.

A test is included that fails before applying this PR and passes with it.
