This week Robert Hardy, our district website accessibility specialist, shares about working with tables in Microsoft Office and Google Docs. Please call Robert with any accessibility questions at Ext. 6105. He is more than happy to talk by phone or schedule a time to meet with you.
One way to make your content more accessible is to include tables alongside graphs or charts. Including a table not only enhances the accessibility of the document, it also allows data to be easily extracted for future use.
When adding a table, it is important to take a few steps to ensure the table is accessible.
Use True Tables
Be sure to use true tables within your documents, rather than tables built using the tab key. To add a table in Microsoft Word or Google Docs, go to Insert > Table and select your table size.
Mark table row and column headers
When reading a table, users will glance up or to the left to see column or row headers. These titles allow a reader to comprehend relationships within the data.
Unfortunately, unless table row and column headers are programmatically defined, they are inaccessible for a screen reader user.
To mark a column or row title in Microsoft Word or PowerPoint:
- Select the table.
- Go to the Table Design ribbon.
- Ensure Header Row and First Column are selected appropriately. Header Row signifies a row of column titles, while First Column denotes row titles.
If your table spreads over multiple pages, you will also want to ensure Repeat Header Rows is selected under the Table Layout ribbon.
Users of Google Docs can use Grackle Docs to create accessible tables:
- Open the Grackle add-on by going to Add-ons > Grackle Docs > Launch. The Grackle Docs add-on will launch on the right side of the screen.
- Grackle will recognize that a table has been included without a header row or column. The error will appear as “Tables must be tagged or marked as layout tables.”
- Click “+Tag” beside the error to enter the Tag Table menu.
- In the Tag Table menu, select the appropriate options from the “Mark first row as header” and/or “Mark first column as header” options.
Avoid blank or merged cells
If you are converting your final document to PDF, it is recommended to avoid blank or merged cells in your table. Blank or merged cells can confuse Adobe Acrobat, creating tables that are misleading or downright inaccessible. Populate blank cells with meaningful data, or with a placeholder such as inserting three hyphens in the cell. If your table has merged cells, usually contained within a header row, consider if the table can be broken into two simple tables.
