Starting a week ago, when I pasted a second table onto a confluence page, the second table width is minimized, so that I have to click the vertical bar to the right of the table and drag it to the right to maximize the table. The second table used to be maximized, same as the first table.
Just to make sure the 2nd table content is not the cause of the change, I pasted the first table again, below itself, and it was minimized.
