How to make tables expand to page width (Writer)

I’ve increased my page width in Writer and now the tables within the document do not stretch across the entire page, they’ve remained the same size.

Is there an way to get the tables to automatically expand to the new page width? The best way I can think of doing it is manually entering the new width to each table. This is pretty laborious. Any improvements?

Thanx

Why table not expand automaticly? I inserted one table and it has same width as a page width. When I change margins or page format (A4 → A3) a table with expands from left margin to right margin. In dialog Table Format Alignment is set to Automatic.

Just set Automatic
