Tables Are Not Accessible. Tables Are Tricky. Tables Are Inflexible. Tables Hurt SEO. Get certified by completing a course today! If you want to report an error, or if you want to make a suggestion, do not hesitate to send us an e-mail:. Links Link Colors Link Bookmarks. Exercise: Add a table row with two table headers. The two table headers should have the value "Name" and "Age". Report Error. Couple this with some confusion about how to make a standard table accessible, and we have a bit of a mess.
I want to qualify that I am talking about data tables, not layout tables. Data tables have two axes of information. If you only have one axis of information, use a list. I am going to give you enough information, hopefully, to make accessible, responsive tables on your own that are not a burden on you nor your users. This part is really easy. I made a CodePen of a simple table , and embedded it below. Not all headers are for columns. Some headers are for a row, and this can be throw off some developers.
It just so happens that WCAG has some guidance for us in technique H Using the scope attribute to associate header cells and data cells in data tables. Generally you want to avoid spanning table cells. This can lead to unnecessarily complex and confusing tables. If you have to, there just happens to be a WCAG technique to support it, specifically H Using id and headers attributes to associate data cells with header cells in data tables.
Once again, the technique offers a sample table, which I recreated on CodePen and also embedded below. You may find it hard to believe, but for a straightforward data table, you probably do not need any ARIA.
Screen readers in particular have been dealing with tables for far longer than the existence of ARIA. Sometimes a table is just a grid of data and sometimes a table is a control widget that users modify or modify its data, such as a spreadsheet.
ARIA has a few roles that define and describe data grids. The definitions that follow come from ARIA 1. Please note that those roles are primarily intended to be used for interactive grids, such as a spreadsheet. In these controls each cell may be editable and can be navigated using a series of keyboard shortcuts.
Since developers were applying grid roles to what should be regular tabular data, ARIA 1. See related grid. The table role is intended for tabular containers which are not interactive.
If the tabular container maintains a selection state, provides its own two-dimensional navigation, or allows the user to rearrange or otherwise manipulate its contents or the display thereof, authors SHOULD use grid or treegrid instead.
Putting all the ARIA roles into practice and understanding which to use can be tricky. You also need to implement all the keyboard support above and more.
