=== Row template ===
{{For|adding a dynamic row number as a table column|#Row numbers}}

Regardless of whether wikitable format or HTML is used, the wikitext of the rows within a table, and sometimes even within a collection of tables, may have much in common, e.g.:
* the basic code for a table row
* code for color, alignment, and sorting mode
* fixed texts such as units
* special formats for sorting
In such a case, it can be useful to create a template that produces the syntax for a table row, with the data as parameters. This can have many advantages:
* easily changing the order of columns, or removing a column
* easily adding a new column if many elements of the new column are left blank (if the column is inserted and the existing fields are unnamed, use a named parameter for the new field to avoid adding blank parameter values to many template calls)
* computing fields from other fields, e.g. population density from population and area
* duplicating content and providing span tags with <code>display: none;</code> for the purpose of having one format for [[Help:Sortable tables|sorting]] and another for display
* easy specification of a format for a whole column, such as color and alignment

Example:

Using {{tlx|Help:Table/example row template}}

<div class="box">
'''Wikitext'''
<syntaxhighlight lang="wikitext" style="display: inline-block;">
{| class="wikitable sortable"
|-
! scope=col | a
! scope=col | b
! scope=col | a/b
{{Help:Table/example row template|  50|200}}
{{Help:Table/example row template|   8| 11}}
{{Help:Table/example row template|1000| 81}}
|}
</syntaxhighlight></div>

<div class="box">
'''Produces'''
{| class="wikitable sortable"
|-
! scope=col | a
! scope=col | b
! scope=col | a/b
{{Help:Table/example row template|  50|200}}
{{Help:Table/example row template|   8| 11}}
{{Help:Table/example row template|1000| 81}}
|}
</div>
