Module:Tabular data/doc

This module provides basic functions for interacting with tabular data on Wikimedia Commons.

Returns the value of the cell at the given row index and column name.

Usage:

A row index of  refers to the first row in the table. A row index of  refers to the last row in the table. It is an error to specify a row index of.

Examples
Latest death toll in c:Data:COVID-19 cases in Santa Clara County, California.tab (regardless of when the table was last updated):

Returns the value of the cell(s) in one or more output columns of the row matching the search key and column.

This function is reminiscent of  macros in popular spreadsheet applications, except that the search key must match exactly. (On the other hand, this means the table does not need to be sorted.)

Usage:

If multiple columns are output without an explicit string format, this function formats the output as a human-readable list.

Some may find Tabular query (which uses this module) an intuitive way to obtain cell data as it resembles a simple SQL query.

Parameters

 * 1 : Page name on Commons with extension but no namespace
 * search_value or search_pattern : Value to find or pattern to match in column
 * search_column : Name of column to search in
 * occurrence : Index of the match to output in case of multiple matching rows. A row index of  refers to the first matching row. A row index of   refers to the last matching row. It is an error to specify a row index of.
 * output_column or output_column1, output_column2, ... : Names of columns to output
 * output_format : String format to format the output

Examples
Total confirmed case count in c:Data:COVID-19 cases in Santa Clara County, California.tab on the day that the county issued a stay-at-home order:

The last day that a hundred or more patients with COVID-19 were in the hospital in c:Data:COVID-19 cases in Santa Clara County, California.tab:

Total number of administrators on all Wikimedia wikis using c:Data:Wikipedia statistics/data.tab:

Number of administrators and users on all Wikimedia wikis using c:Data:Wikipedia statistics/data.tab:

''Note: Wikipedia statistics are shown as an illustration only. In practice, there is a high-performance module to access Wikipedia statistics.''

Returns the entire data table as a (rather plain) table.

Usage:

Implementation notes
The implementation of this function incorporates n/a (to represent null values), yes (true), and no (false). The templates themselves cannot be reused because they are incompatible with the  library, which builds the table using an HTML DOM instead of pure wikitext.

Internationalization
You can most likely port this template to a wiki in another language without making major modifications. The  function automatically localizes the table's description, column titles, and license name into the wiki's content language. It also formats numbers according to the content language. However, you should localize the cells representing,  , and   by changing the values in the  ,  , and   variables to match the wiki's own yes, no, and n/a templates, respectively.
