Editing Help:Table (section)

=== Class ===

One or more classes may be added to the [[#Begin and end delimiters|§&nbsp;Begin-table delimiter]] line at the top of the table, and may be used to supply predefined style to the table. The wikicode table {{kbd|class}} attribute [[Help:Basic table markup#How tables are formed|corresponds directly]] to the "{{kbd|class}}" [[HTML attribute|attribute of the HTML]] <code>&lt;table></code> element. To add multiple classes to a table, place them all on the same line, embedded in double quotes and separated by a space:
<syntaxhighlight lang=wikitext class=grid>
{| class="wikitable sortable collapsible"
</syntaxhighlight>

Some predefined classes are:

* {{kbd|wikitable}} – provides column headers with bold font on shaded background, and other common style. See [[Help:Table/Advanced#Horizontal alignment in cells|here]] for details. This class should be used for almost all tables, unless there is a reason not to.
* {{kbd|sortable}} – adds up & down icons to column headers which enable sorting the table on a given column. See [[Help:Sortable tables#Creating sortable tables|sortable tables]].
* {{kbd|mw-collapsible}} – See [[Help:Table/Advanced#Collapsible tables|collapsible tables]].{{efn|group=note|Collapsible tables: the class {{kbd|collapsible}} is available, but no longer recommended; use {{kbd|mw-collapsible}} instead. See [[Help:Table/Advanced#Collapsible tables|here]] for further details.}}
* {{kbd|plainrowheaders}} – applies left-aligned and normal-weight formatting of row headers. See [[Wikipedia:Manual of Style/Accessibility/Data tables tutorial#Layout of table headers|Table header layout]]. Must be placed after ''wikitable'' if they both appear in the class declaration.
* {{kbd|floatright}} – same as applying <code><nowiki>style="float:right; clear:right; margin-left:8px"</nowiki></code> to the entire table
* {{kbd|floatleft}} – same as applying <code><nowiki>style="float:left; clear:left; margin-right:8px"</nowiki></code> to the entire table

Note: [[Template:Table]] may also be used to apply classes to the [[#Begin and end delimiters|§&nbsp;Begin-table delimiter]] line.
