In this example, the scope attribute defines what the headers describe, column or row, which screen readers use. You can add a table using HTML rather than wiki markup, as described at HTML element#Tables. However, HTML tables are discouraged because wikitables are easier to customize and maintain, as described at manual of style on tables.
An example of an HTML table containing 4 cells: Cell 1: Cell 2: ... In this case the tags colspan and/or rowspan are used - where they are set to a number.
For complex layouts, rowspan and colspan may be used, but again it is sometimes simpler and more maintainable to use nested tables. Nested tables must start on a new line. In the following example, five different tables are shown nested inside the cells of a sixth, main table. None has any header cells.
If you use tables for two-dimensional graphics you might discover a "feature" in HTML that promotes grey hair. It can affect both rows and columns, depending on the use of either rowspan or colspan. In this 7-row table three cells are assigned a rowspan of 3, but the table totals 6 rows. Where is row 4? There is a row 5-4!
This also applies to other coding approaches, such as divs with CSS styling, or rowspan and colspan HTML cell attributes. Nesting data tables with header cells also makes it difficult for assistive readers to parse them sensibly, and should be avoided.
For columns, one uses |colspan=n | content, whereas for rows, one uses |rowspan=m | content. In the table code, one must leave out the cells that are covered by such a span. The resulting column- and row-counting must fit. Tables can have cells spanning multiple rows, using |rowspan=n. The number of rows must be indicated with each use of rowspan.
This information, the colors and default texts are found in the table below. Important: If you want to use other attributes for the table cells, e.g. colspan, rowspan, or style, they need to be put before the template call, and there must be no vertical bar (aka pipe) | in-between them:
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.
