Andoza:Diagonal split header 2

Andoza hujjati

Foydalanish

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}}.

There are two variants of the template with different – and sadly incompatible – features:

• Template:Diagonal split header allows splitting the background color (see below)
• Template:Diagonal split header 2 produces a line with consistent thickness in very large table cells (see below)

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 ( ), line breaks (<br />), 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

Diagonal split header only

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.

You may also indicate a second color in the fourth parameter (its default is the same as the third parameter), the first color being used for the lower left half of the cell, the second color being used for the upper right half of the cell.

Prefix it with | for data cells instead of ! for header cells, as in this Friend or Foe? payoff matrix:

Example

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

Code

Wiki markup 

{| class="wikitable" style="margin:0 auto;text-align:center;"
! {{diagonal split header| Pair 1 | {{color|#900|Pair 2}} | cyan | yellow}}
! style="width:6em;background:yellow;"| {{color|#900|"Friend" (cooperate)}}
! style="width:6em;background:yellow;"| {{color|#900|"Foe" (defect)}}
|-
! style="width:6em;background:cyan "| "Friend" (cooperate)
| {{diagonal split header| 1 | {{color|#900|1}} | transparent}}
| {{diagonal split header| 0 | {{color|#900|2}} | pink | palegreen}}
|-
! style="width:6em;background:cyan "| "Foe" (defect)
| {{diagonal split header| 2 | {{color|#900|0}} | palegreen | pink}}
| {{diagonal split header| 0 | {{color|#900|0}} | pink}}
|}

Spanning columns and rows, and collapsible and sortable tables

Diagonal split header 2 recommended

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 2 ...}}. 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.

In large table cells like this, use Diagonal split header 2 to produce a better-looking line, with the same thickness as the cell borders:

Example

n City		2023	2024
		Dec	Jan	Feb
Roma	Rome	8	1	6
Venezia	Venice	3	5	7
Firenze	Florence	4	9	2

Code

Wiki markup 

{| class="wikitable sortable mw-collapsible" style="margin:0 auto;text-align:center;"
! colspan="2" rowspan="2" {{diagonal split header 2|City|''n''}}
! {{#expr:{{CURRENTYEAR}} - 1}}
! colspan="2"|{{CURRENTYEAR}} 
|-
! Dec !! Jan !! Feb
|-
! Roma !! Rome
| 8 || 1 || 6
|-
! Venezia !! Venice
| 3 || 5 || 7
|-
! Firenze !! Florence
| 4 || 9 || 2
|}

Technical notes

• It is possible to create a version without the line-overrun per Krautzberger. This one works by drawing a line and using a 2x2 CSS grid with the bottom-left and top-right corners.

  See caniuse for support of the required css-grid feature; compare with (unprefixed) css-gradients underlying the current implementation.

• Neither implementation supports laying out text along the diagonal, as the browser is unaware of the triangular shape. CSS-shapes may be a solution, but the easier shape-inside approach is yet to be standardized.
