Lock table cells to their default size regardless of content

Answer 1

You can also lock the cells to a percentage, in order to maintain responsiveness, eg:

  td:first-child, th:first-child {
    width: 20%;
  }
  // assuming you have 8 remaining columns (20 + 10*8 = 100%)
  td:not(:first-child), th:not(:first-child) {
    width: 10%;
  }
