The above is an example of a simple data table of a work schedule. The table has six columns and three rows. The column headers are the days of the week Monday through Friday. The row headers are “Start Time” and “End Time”. Each day of the week has two times listed, one for when to be at work and one for when to leave.

For simple data tables where there is a one-to-one relationship between a data cell and a row/column header, The Scope attribute can be used to associate the header with the cell. There are two methods to properly associate the cells; using the Table Editor features (recommended) or editing the properties of each cell through the Tags pane. The steps for both methods are explained below.

Recommended Approach: Using the Table Editor:

  1. Activate the TURO tool under Accessibility in the Tools pane.
  2. Activate the Context menu of the table.
  3. Select Table Editor.
    Table Editor highlighted on the context menu
  4. Activate the Context menu of the table header cell that needs to be marked as a header.
  5. Select Table Cell Properties.
  6. Confirm the Table Cell Properties dialog appears.
  7. Select the Header Cell radio button under Type in the dialog.
    Table Cell Properties dialog with "Header Cell" radio button selected
  8. Select the appropriate Scope - Row, Column or Both from the Scope combo box.
  9. Navigate to and activate the OK button.
  10. Repeat the process for each row and column header.

Method Two: Editing Properties and Attribute Objects:

  1. Locate the header text in the Tags pane.
  2. Select Properties… from the Context menu.
  3. Confirm the TouchUp Properties dialog appears and that Tag is the active tab.
  4. Confirm Table Header Cell is selected in the Type combo box.
  5. Navigate to and activate the Edit Attribute Objects… button.
  6. Confirm the Attributes dialog appears.
  7. Expand all Attribute Objects.
  8. Navigate to and activate the New Item button.
  9. Confirm and select the new item that begins with /O.
    • If the /O item has /Layout after it, the item needs to be changed to Table so that the application can apply the proper structure.
    • Navigate to and activate the Change Item button.
    • Enter Table (case sensitive) in the Value edit field.
    • Navigate to and activate the OK button.
    • Confirm the item now reads /O /Table.
  10. Select the /Attribute Object 1 item.
  11. Navigate to and activate the New Item button again.
  12. Confirm the Add Key and Value dialog appears.
  13. Enter the value Scope (case sensitive) in the Key field.
  14. Enter the value Row, Column or Both (case sensitive) in the Value field.
  15. Select the value String in the Value Type combo box.
  16. Navigate to and activate the OK button.
  17. Confirm the structure of the Attributes dialog is: Attribute Objects, nested Attribute Objects 1, further nested /O /Table and /Scope (Row), /Scope (Column) or /Scope (Both).
    Attributes dialog with the proper structure
  18. Navigate to and activate the OK button in the Attributes dialog.
  19. Navigate to and activate the Close button in the TouchUp Properties dialog.
