 cell to	|World      |
	  force the table to be a	+-----------+
	  rectangle.

	> table5 :: BlockTable String
	> table5 = table1 %-% table4	+-----%-----+-----+
					|Hello%Hello|World|
	  Notice the padding on the	|     %-----+-----+
	  leftmost cell, again to	|     %World      |
	  force the table to be a	+-----%-----------+
	  rectangle.
 
   Now the table can be rendered with processTable, for example:
	Main> processTable table5
	[[("Hello",(1,2)),
	  ("Hello",(1,1)),
	  ("World",(1,1))],
