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.

  1. The Rule: Every column must have the same number of rows, and every row must have the same number of columns.
  2. 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.
  3. 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.

  1. Click anywhere inside the table.
  2. Go to the Table Design tab in the ribbon.
  3. In the Table Style Options group, check Header Row.
  4. 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.

  1. Right‑click the outer border of the table.
  2. Select View Alt Text.
  3. 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.

  1. Go to Home > Arrange > Selection Pane.
  2. Ensure the table is positioned logically in the reading order, usually after introductory text and before concluding content.
  3. 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.

  1. The Right Way: Use Insert > Table and select a grid size.
  2. Why: Drawn tables are not recognized as tables by screen readers and are announced as unrelated lines and text.

Step 6: Validation

  1. Go to Review and select Check Accessibility.
  2. Fix warnings such as “Missing table header” or “No header row specified.”
  3. 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?
