Screen reader not reading column name when the column header is sorted

When using either Jaws or NVDA screen readers with the grid, and the column header is being sorted (it doesn't matter whether ascending or descending), that column name is no longer read by the screen reader. Instead it reads out "sorted ascending (or descending)".  I would expect that it should read out the column name and then the sort.  For example:  "Name sorted ascending".  When the column is not sorted, then the column name is read out correctly. 

 

It should also be noted that this happens whether the focus is on the header cell or a regular cell for that column.

Hi Mike,

I am testing with NVDA version 2021.3.1. The reader indeed reads the sort operation - be that ascending, descending or no sorting. However, hovering over the column header text afterwards is still read correctly on my end. It seems that there is no issue with reading the content of the column cells as well.

Please see video attached of the result I am getting.

Hi Nadezha,

 

Thanks for the response. Unfortunately, hovering with the mouse is not the same as navigating with the keyboard.  Screen reader users are usually blind and are not able to use the mouse, so they rely on keyboard navigation. If you look at your Keyboard Navigation demo for the grid, and use NVDA with the keyboard, you will see that the column header is not read when that column is sorted.

In the screenshot above you can see that the Unit Price is sorted ascending, but if you use NVDA with the keyboard, it doesn't get read.  Here is what the NVDA Speech Viewer shows when I navigate the header row, and then navigate the first row of data. (Note: the Speech Viewer displays in text what is read by the screen reader.  It's not on by default but you can enable it in NVDA's settings)

Data table  table
Product Name Product Name column filter menu settings  column header  subMenu  row 1  Product Name Product Name column filter menu settings  column 2
Sorted in ascending order  column header  subMenu  sorted ascending  row 1  Sorted in ascending order  column 3
Discontinued Discontinued column filter menu settings  column header  subMenu  row 1  Discontinued Discontinued column filter menu settings  column 4
False  row 2  Discontinued Discontinued column filter menu settings  column 4
2.50  row 2  Sorted in ascending order  column 3
Geitost  row 2  Product Name Product Name column filter menu settings  column 2

 

I'm using the arrow keys to navigate, and as you can see above, I start with the Product Name, and it gets read. When I then arrow to the Unit Price, It just says Sorted in ascending order, but never actually reads the name.  The same is true on the data row.

Thanks,

Mike

Hi Mike,

Thank you for the additional details! Indeed, this behavior is reproducible using the keyboard navigation. In the meantime, another client has logged a bug report on the matter in our public portal:
