What to Look For (Everyone)
- Is the table showing real data?
- Does the first row label columns?
- Would it make sense if read out loud?
Examples of 鈥渞eal data鈥�
- schedules
- comparisons
- lists with multiple columns
- anything where rows and columns represent relationships
NOT real data:
- lining up text in columns
- placing images next to paragraphs
- spacing content
- creating visual layouts
- If the table is just making things look neat, it鈥檚 not real data.
That is a layout table 鈥� and layout tables should not be used.
Why This Matters
Screen readers read tables cell by cell. Without headers, data becomes confusing.
How to Fix It (Editors)
- Use tables only for data.
- Include header rows.
- Avoid merged cells.
- Do not use tables for layout.
Do / Don鈥檛
DO
- Keep tables simple.
顿翱狈鈥橳
- Use tables for positioning content such as text and images.
If You Must Use Merged Cells
Sometimes merged cells feel unavoidable (for example, grouping semesters or categories).
If that happens:
- Keep merging to an absolute minimum.
- Make sure headers still clearly describe every column.
- Avoid merging data cells whenever possible.
- Add explanatory text above the table to explain structure.
