Table Example: ARIA table made using HTML div and span elements. Less than or equal to the total number of columns. Implement focus management so the keyboard tab sequence includes one stop for the toolbar and arrow keys move focus among the controls in the toolbar. assistive technologies with the correct data cell header information A web application has a frequently used function that is similar to a browser function.
