Only to be sure. The ability to create and customize a bottom border for a table when the footer is disabled is still pending, isn't it?
Furthermore, I am experiencing another bug with the customization of the tables. In the Inspector Panel (Style), when you select, within Table Styles, "Show caption above table", the sample figure above goes down to show the caption above the table, and the footer disappears almost entirely being difficult to try to select part of their elements for customization.
Indeed, I have observed that in the document "Getting Started" there is a screen capture that shows that, even when Table caption is placed below, the caption appear in the table above. In my case this caption doesn't appear.
