Table layout
You can change the width via the Edit Table feature. As you select the table you will see some action buttons appear in the bottom right of the Figma panel. One of them is the 'Edit Table' button. It will open a panel where you can adjust all styling options.
All columns will automatically adjust to the new width.
During this tutorial, you will notice that depending on the element you have selected, the action buttons at the bottom right change accordingly.
