Narrator is not accessing the readonly grid content

[gyz0072004]

Describe the bug

When setting a grid to read only and use narrator to access the grid, narrator could only focus on the whole data grid. It could not focus onto each cell. As a result, users with visual disability will not be able to know the grid content.

Expected behavior

Please use the built-in narrator with windows to see the behavior.

Expect the narrator focus could focus to the grid cells just like the tab focus.

Screenshots

The narrator focus is with blue border, and the tab focus is with black border. we can see that narrator could only focus to the whole table, while tab focuses to the grid cell.
