Video capture showing the problem
The Clone formatting tool does not work in Impress tables. It has 2 main problems:
1) It only has effect inside the same table; so there is no way to clone the formatting of a portion of one table and apply it to another table.
2) Even within the same table, results are not consistent (see attached video). If you try to clone cells and apply the formatting to other cells, the source format is not applied as expected.
