Why you might want to create a template like this:

Regardless of whether wikitext or HTML is used, rows within a table, and sometimes even within a collection of tables, may have much in common, e.g.:

• the basic markup 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 display: none; for the purpose of having one format for sorting and another for display
• easy specification of a format for a whole column, such as color and alignment

What this template does:

1. Accepts two numeric parameters.
2. Structures the output as a table row with three data cells.
   • First two cells hold the parameters in order.
   • Third cell holds the first divided by the second.
3. Transcludes at the point of use.
