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.
It is possible to create tables with cells that stretch over two or more columns or rows (also known as merged cells). 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.
The first uses colspan="2" <-- This row has three table data cells, but one spans two rows because it uses rowspan="2" <-- This row has only two table data cells, because its first is being taken up
In the code, the cell | colspan="2" | A spans two columns. Note that, in the next column, a cell expected to contain "B" does not exist. Similar: in the code, cell | rowspan="2" | BBB spans two rows. A cell expected to contain "BBBB" does not exist.
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!
! colspan="2" {{vert header|cellstyle=background-color:gold|Your text here}} – produces a header spanning two columns, with a gold background; use no vertical bar after colspan; You can also use the ! {{verth|Your text here}} shorthand. An example below (from Help:Sortable tables) with headers that span rows or columns (using rowspan and ...

This is the same as the maximum number of linearly independent rows that can be chosen from the matrix, or equivalently the number of pivots. For example, the 3 × 3 matrix in the example above has rank two. [9] The rank of a matrix is also equal to the dimension of the column space.
