Summary
Review of what you've learned



Whether you've just inserted a new table, or are editing an existing one, changing the text in the table cells determines what the table looks like to a reader. But you can do more than just change text.

A table consists of the following basic elements, all of which you can modify:

{| start Besides beginning the table, this is also where the table's class is defined – for example, class="wikitable". A table's "class" applies standard Wikipedia formatting to that table. The two most commonly used classes are "wikitable" and "wikitable sortable"; the latter allows the reader to sort the table by clicking on the header cell of any column.
|+ caption Required for accessibility purposes on data tables, and placed only between the table start and the first table row.
! header cell Optional. Each header cell starts with a new line and a single exclamation mark (!), or several header cells can be placed consecutively on the same line between double exclamation marks (!!).
|- new row To begin a new row of cells, use a single vertical bar (|) and a hyphen (-).
| new cell
in row
To add a new cell in a row, start each new cell with a new line and a single vertical bar (|), or several cells can be placed consecutively on the same line between double vertical bars (||).
|} end To end the table, use a single vertical bar (|) and a left facing curly brace (}) alone on a new line.

Blank spaces at the beginning and end of a cell are ignored.

Layout

When you edit an existing table, you'll probably see one of two common ways that the table is laid out:

To a reader, both of the above examples will look the same:

Caption
Header C1 Header C2 Header C3
R1C1 R1C2 R1C3
R2C1 R2C2 R2C3
