+
+ BlockTable, -- abstract
+
+-- Contruction Functions:
+
+ single,
+ empty,
+ above,

+
+infixr 4 `beside`
+infixr 3 `above`
+
+-- These combinators can be used to build formated 2D tables.
+-- The specific target useage is for HTML table generation.
+
+{-
+ Examples of use:
+
+ > table1 :: BlockTable String
+ > table1 = single "Hello" +-----+
+ |Hello|
+ This is a 1x1 cell +-----+
+ Note: single has type
+
+ single :: a -> BlockTable a
+
+ So the cells can contain anything.
+
+ > table2 :: BlockTable String
+ > table2 = single "World" +-----+
+ |World|
+ +-----+
+
+
+ > table3 :: BlockTable String
+ > table3 = table1 %-% table2 +-----%-----+
+ |Hello%World|
+ % is used to indicate +-----%-----+
+ the join edge between
+ the two Tables.
+
+ > table4 :: BlockTable String
+ > table4 = table3 %/% table2 +-----+-----+
+ |Hello|World|
+ Notice the padding on the %%%%%%%%%%%%%
+ smaller (bottom) 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))],
+ [("World",(2,1))]] :: [[([Char],(Int,Int))]]
