Dark Lines in Table

I have made a two column table in a document with about 15 or so rows. The first two or three rows and columns have dark black lines separating the cells, while the rest of the table has lighter lines. How can I format the table so that the lines separating the cells are a uniform shade?

  1. Select the entire table (click first cell and drag to last cell with your mouse/trackpad)

  2. Format > Table > Table…

  3. Choose the Cell Border settings you want from the pop-up box (as below)


Your solution worked; thank you.

Happy to help.
