Now it is impossible to move rows or columns in a table.
The shortcut ctrl+shift+up/down does not work on tables for moving rows (it works on usual paragraphs). Actually a more standard shortcut is shift+alt+up/down (not sure why you have chosen ctrl instead of alt) -- I think it is better because ctrl is usually used for selection.
The most important feature is moving rows. At least by using keyboard shortcut: ctrl+shift+up/down (or alt).
Second priority is moving columns. At least by using keyboard shortcut: ctrl+shift+left/right (or alt).
Alternatively using drag&drop (I personally like keyboard shortcuts).
