Some screen readers announce "has formula" both in native application tables (e.g. LibreOffice Calc and Writer) and in web applications (e.g. Google Sheets).

In native applications, the screen reader is able to identify the presence and contents of the formula through its exposure in the accessibility tree. The user, in response to hearing "has formula", can then use the screen reader's command to obtain that formula.

In web applications (e.g. Google Sheets) that support accessible formulas, the "has formula" announcement comes via live regions. But the screen reader command to read the current formula subsequently fails, which can be confusing to the user who then has to figure out how to access the formula's contents for that particular web app.

I'd like the ARIA Working Group to consider adding an attribute for table-cell formulas so that screen readers can provide a consistent user experience.

Thanks in advance!
