Usage

This template simulates a table header cell split diagonally, a device often used to compactly label headers of rows and columns, as in this example:

To 
From
Solid Liquid Gas
Solid Solid-solid transformation Melting Sublimation
Liquid Freezing Boiling/evaporation
Gas Deposition Condensation

To use it, create a header cell using ! followed by {{diagonal split header|NATURE-OF-ROW-HEADERS|NATURE-OF-COLUMN-HEADERS}}.

As the effect is achieved by drawing a diagonal line across the cell, the two headers are still part of the same cell and can easily overrun the line. A remedy is to pad the headers with non-breaking spaces (&nbsp;), line breaks Template:Nobr and/or CSS (escape = signs as {{=}}), as in the example above. The template user is responsible for checking that it does not overrun on common Web browsers.

Background colour and non-header cells

A third parameter can be added to change the background colour from the standard header cell colour. Changing it to transparent (or another colour such as white, or #ffffff) lets the template be applied to non-header cells. Prefix it with | instead of !, as in this Friend or Foe? payoff matrix:

Pair 2
Pair 1
"Friend"
(cooperate)
"Foe"
(defect)
"Friend"
(cooperate)
1
1
2
0
"Foe"
(defect)
0
2
0
0

Spanning columns and rows, and collapsible and sortable tables

The template is compatible with collapsible tables, and cells using colspan or rowspan, in which case place the colspan/rowspan attribute between ! and {{diagonal split header ...}}. It is not compatible with sortable tables, as the sort arrows are not drawn, but this problem can be resolved by using a second header row:
