I’ve upgraded to 6.2.4.2. Now, when I press tab or right arrow to progress to the next cell in a table, the previous cell is autoformatted: the placement of the number changes. (I want it upper left in the cell; it is now moved to lower right for some reason.) I can’t identify any way to shut off autoformat for tables, or to tell LO to not autoformat the table. I can’t even find a way to re-define the position of the number, to tell 6.2.4.2 to leave it where I want it. I have no idea how to get the table back to the way I had it before I upgraded.
Edit your question with following information: what is the paragraph style of cell content (displayed in the leftmost box of the toolbar)? Have you added manual formatting to your cells?
In what file format did you save your file?
