Hi Anvil thanks for posting on the Community!

Please refer to the Add Remove and Resize Tables and Rows section of our Tables article from the Help Center for details on resizing your table.

Specifically please note that if you hover over the border of a column or row the cursor will change to a double headed arrow. Click and drag the border in or out. Resize the entire table by clicking and dragging one of the corners of the table.
Note: As you increase row size the table size will increase. As you change column size the table size will stay the same. This means that other column sizes may change.

The options for resizing are limited to either the entire table or to an individual row or column at one time. Unfortunately there is not a way to resize multiple rows at once or a way to make then automatically match in size. If that is a feature you would be interested in, we’d love to hear more details about your use case or what you’d like to see in this experience posted in the Product Feedback section of the community - from here, other users can upvote it and add details of their own.

For more information on how Lucid manages feedback via this community, take a look at this post.

Thanks!
