Looking at https://help.libreoffice.org/Common/Copying_Attributes_With_the_Clone_Formatting_Tool I found that Impress tables are not covered. The only reference to Impress is re "Drawing object is selected". I believe changing "Writer table or cells are selected" by "Writer or Impress table or cells" would be appropriate (according to my testing with Impress)?

This issue is still valid in LO 7.4. See: https://help.libreoffice.org/7.4/en-US/text/shared/guide/paintbrush.html?DbPAR=SHARED#bm_id380260 Wee need an entry for "Impress table or cells are selected". The main problem is that the Clone tool for tables in Impress is too buggy in its current format. I ran a few tests here and nothing worked: 1) It only has any effect inside the same table (does not work across different tables) 2) Even inside the same table results are completely unexpected Wee need a separate bug report to fix these issues before documenting the Clone tool for Impress tables.
