Merging multiple tables into one

[kajto3]

I have 3 tables, each having the same amount of columns, but variable column headers and row amounts.
My goal is to create a single table that looks exactly like 3 tables printed one under another, but I would also like to keep the width of the widest row and headers with their separators/borders.
I keep my tables simplest as possible, this is an example:

 ALLIES     | ping |   xp 
--------------------------
 Statler    |    0 | 1068 
 Stangepork |    0 |  881 
 Scooter    |    0 |  667 
--------------------------
 AXIS     | ping |  xp 
-----------------------
 Wontkins |    0 | 977 
 Snerf    |    0 | 963 
 Animal   |    0 | 659 
-----------------------
 SPECTATOR      | ping | xp 
----------------------------
 SuperPlayerDE  |   48 |  0 
----------------------------

Expected result:

 ALLIES         | ping |   xp 
------------------------------
 Statler        |    0 | 1068 
 Stangepork     |    0 |  881 
 Scooter        |    0 |  667 
------------------------------
 AXIS           | ping |   xp 
------------------------------
 Wontkins       |    0 |  977 
 Snerf          |    0 |  963 
 Animal         |    0 |  659 
------------------------------
 SPECTATOR      | ping |   xp 
------------------------------
 SuperPlayerDE  |   48 |    0 
------------------------------

Another acceptable solution would be to keep 3 tables but somehow set a min width based on the widest row.
