how do I change to responsive tables when already selecting responsive...

[Minami Hoshino]

I have a table selecting "responsive" in the top left corner, but when I write into the cells, the tables expand to the right, and they do not automatically responsively adjust to fit into the page as per attached. How can I resolve? 

I copied this table format from a colleague, and her tables are adjusting automatically responsively without any additional editing, whereas my tables aren't.

Thank you for your assistance in advance.

In the new editor table widths are determined by the user.  When you add them by default they will all be equal.  If you choose to change the width of a column it will remain the width you gave it. If you do not give it a width it will be responsive and change with the screen size.   You can learn more about tables in the new editor here: https://support.atlassian.com/confluence-cloud/docs/add-formatting-to-your-page/#Addformattingtoyourpage-tables
