Just focus on the table for assert* methods. This is the one category that users will need to look-up over and over again. The goal is to make the docs more usable, not more voluminous.
Also, I suggest finding meaningful groupings (don't stick with alpha order) and including a short plain assert-statement equivalents to show what the methods actual do (this is important because many are new, some are obscure, and not all have obvious semantics):
 | assertEqual(x, y) | assert x == y |
 | assertGreaterThan(x, y) | assert x > y |
 | assertItemsEqual(act, exp) | assert sorted(exp) == sorted(act) |
