UETOOL-281 - Improve data table workflows UETOOL-304 - Data table editor doesn't support undo/redo properly Undo/redo is now supported when adding, removing, moving, or renaming rows, as well as changing the properties of any given data table row. This also adds highlighting when filtering the data table view, and slightly adjusts the selected row color so it doesn't blend into the background, as well as ensuring the data table is emptied prior to loading (as undo/redo loads on top of an existing object).
