The best way to deal with this is:

* Table Test

  |-------------+------|
  | unrelated 1 | ~>=~ |
  | Test1       | ~=~  |
  | unrelated 2 | ~<=~ |
  | Test2       | ~==~ |
  | unrelated 3 | ~-=~ |
  | Test3       | ~:=~ |
  | unrelated 4 | ~>=~ |
  | Test4       | ~=~  |
  | unrelated 5 | ~<=~ |
  | Test5       | ~==~ |
  | unrelated 6 | ~-=~ |
  | Test6       | ~:=~ |
  |-------------+------|

etc
