Power Point - Simple Tables
PowerPoint Accessibility Technical Standard 7: Simple Tables
The “Why” Behind the Standard
Sighted users can visually scan rows and columns to understand a table. Screen‑reader users, however, navigate tables cell by cell. If a table is not properly structured—such as having merged cells or missing headers— the screen reader announces a series of values without context, making the data difficult or impossible to interpret.
The Goal: Use a simple, consistent grid and define header rows so screen readers can announce the category for each data point (for example, “Year: 2026, Enrollment: 15,000”).
Step 1: Use a Simple Grid (Avoid Merged Cells)
Complex tables with merged or split cells break the logical structure that assistive technology relies on.
- The Rule: Every column must have the same number of rows, and every row must have the same number of columns.
- Avoid: Do not merge cells to create a title row inside the table. Place the title in the Slide Title or in text above the table.
- Action: If a table becomes too complex, split it into two or more smaller tables.
Step 2: Define the Header Row
Header rows tell the screen reader which cells contain labels for the data below.
- Click anywhere inside the table.
- Go to the Table Design tab in the ribbon.
- In the Table Style Options group, check Header Row.
- If row labels appear on the left, also check First Column.
Step 3: Add Alt Text to the Table
Tables need a brief summary so users can decide whether to explore the data in detail.
- Right‑click the outer border of the table.
- Select View Alt Text.
- Provide a concise summary, such as: “Table comparing tuition costs at five local community colleges for the 2026 academic year.”
Step 4: Check the Reading Order
Tables must appear in the correct position within the Selection Pane.
- Go to Home > Arrange > Selection Pane.
- Ensure the table is positioned logically in the reading order, usually after introductory text and before concluding content.
- The Logic: When reached, the screen reader announces the table size (for example, “Table with three columns and four rows”).
Step 5: Avoid “Drawing” Tables
Never create tables by drawing lines or using the Draw Table tool.
- The Right Way: Use Insert > Table and select a grid size.
- Why: Drawn tables are not recognized as tables by screen readers and are announced as unrelated lines and text.
Step 6: Validation
- Go to Review and select Check Accessibility.
- Fix warnings such as “Missing table header” or “No header row specified.”
- Merged or split cells are flagged as critical errors and must be corrected.
Quick Checklist for Tables
- [ ] Did I use Insert > Table instead of drawing a table?
- [ ] Is the Header Row option enabled?
- [ ] Are there no merged or split cells?
- [ ] Did I provide a concise alt text summary for the table?
- [ ] If the table was complex, did I break it into smaller tables?
