I added a numbering column to a table on a wiki page by clicking the icon for doing so. Now, I can't remove it. If I try to delete the numbering the column, it deletes the column to the right. If I add an intervening col and then try to delete the numbering column, the text in the table is scrambled. Thinking it might have to do with the table filter, I tried to remove the filter, it removed the table. Any advice?
