HTML tables <table> should be used sparingly, and only for information that truly belongs in a table. Tables should not be used just for layout.
Also, you should not be hand-coding very large tables, tables that need to be updated regularly, or tables that re-create data that is stored elsewhere. If you find yourself spending a lot of time keeping tables up-to-date, or you need advanced functionality (like the ability to sort by column) you should contact library IT about creating a more sustainable solution.
Currently, tables have the default YaleSites styling, and all tags unique to tables are supported:
|thead||th 1||th 2|
|tbody||td 1||td 2|
|tr 2||td 1||td 2|
|tfoot||td 1||td 2|
