Hi there!
To make the outside border of a table thicker than the lines inside, you can follow these steps:
- Select the table by clicking anywhere inside it.
- Go to the "Design" tab in the ribbon at the top of the screen.
- In the "Table Styles" section, click the arrow in the bottom right corner to open the "Borders" menu.
- In the "Borders" menu, click "Borders and Shading" at the bottom.
- In the "Borders and Shading" dialog box, click the "Borders" tab.
- Under "Setting," choose "Custom" from the drop-down menu.
- Under "Style," choose the type of line you want for the outside border.
- Under "Width," choose the thickness you want for the outside border.
- Under "Preview," click the "Outside Borders" button to select only the outside borders of the table.
- Click "OK" to apply the changes.
This should make the outside border of your table thicker than the lines inside.
