In this example, the scope attribute defines what the headers describe, column or row, which screen readers use. You can add a table using HTML rather than wiki markup, as described at HTML element#Tables. However, HTML tables are discouraged because wikitables are easier to customize and maintain, as described at manual of style on tables.
Crosswalk tables are often employed within or in parallel to enterprise systems, especially when multiple systems are interfaced or when the system includes legacy system data. In the context of Interfaces, they function as an internal extract, transform, load (ETL) mechanism. For example, this is a metadata crosswalk from MARC standards to ...
All data tables need a table caption that succinctly describes what the table is about. [ WCAG 2 ] It plays the role of a table heading, and is recommended as a best practice.

The term "schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases). The formal definition of a database schema is a set of formulas (sentences) called integrity constraints imposed on a database.
Overusing tables, especially with complex coding, can make pages harder to edit and maintain, so careful consideration should be given to their structure. Maintain accessibility when creating tables by using specific table tags to help users navigate the data and captions to clearly identify and describe tables. Avoid relying solely on ...
