The default implementation of tables in HTML5 Forms uses HTML DIV elements to render a table. Rendering involves using ARIA roles to satisfy the accessibility requirements.
To avoid accessibility issues with screen-readers which do not fully support the ARIA-roles used with data-tables, HTML5 Forms provides an alternate rendition for the tables. These tables are based on the new table format introduced in Designer which also supports:
To use the new format in HTML5 Forms, mark the table as complex. To mark the table as complex, add
extras tag in the XML source of table subform as follows:
</extras> <text name="complexTable">1</text> </extras>
The tables which are marked as complexTable follow the native HTML rendition, and provide better accessibility support for certain screen readers. To create a row span, select consecutive cells of a table in the same column, right-click on the selection, and then click Merge Cells.
Creating a row-span works for leftmost cells only.
To mark a row as row header, select all cells in the row, right-click on the selection, and then click Mark Header.
To mark a cell as column header, select any cell in the column, right-click on the selection, and then click Mark Header.
