Module:Table row counter
MyWikiBiz, Author Your Legacy — Sunday September 08, 2024
Jump to navigationJump to searchThis module implements the {{table row counter}} template.
Usage from wikitext
This module can be used from wikitext in the same way as the {{table row counter}} template, by simply using Template:Braces
in place of Template:Braces
.
Usage from Lua modules
To use this module from other Lua modules, first load the module.
<syntaxhighlight lang="lua"> local mTRC = require('Module:Table row counter') </syntaxhighlight>
You can then count table rows by using the _main function.
<syntaxhighlight lang="lua"> mTRC._main(args) </syntaxhighlight>
args is a table containing the module arguments. See the template documentation for more information about the available arguments, and for general caveats about this module's use.
