@zahra21 yes in Excel this is supported. In Libre Calc this is still an issue. Right?

It seems that LibreOffice developer Tamás Zolnai committed a patch related to this issue (adding selection-changed event).

In this case, LibreOffice developer said "selection change event is added."
But, this patch does not fix screen reader NVDA "report selected cell coordinates".
What should we do (Let LibreOffice developer know the gap)?
Or how to use this "selection change event to implement feature "report selected cell coordinates?

Is anyone working on this? It's still an issue in libreoffice 7.0.2 and nvda 2020.3
A fix would be greatly appreciated.

Apart from the patch refered to in #6897 (comment), it looks like LibreOffice people aren't that accessibility minded unfortunately.

it looks like LibreOffice people aren't that accessibility minded unfortunately.

Do we have examples of this? Were the correct bugs ever filed against libreoffice to make them aware of the issue? I'm not a developer so can't file the bugs myself as i wouldn't know what to point at or what the behind the seens tech speak would be.

A number of accessibility bugs filed, many issues here with the app/libreoffice label have links to bugs on the issue tracker for libreoffice.

I have tried to reach out to a few developers who work on libreoffice, for the record NV Access is willing to work with libreoffice developers to help solve these issues. They can contact us via info@nvaccess.org to start a conversation.

There is an issue on LibreOfice's bug tracker for this, which goes back to 2016: https://bugs.documentfoundation.org/show_bug.cgi?id=100086 (with references to an older issue again).

DEMO: soffice: Announce coordinates of selected cells (nvaccess#6897)
31dbfaa 
This is just a demo to show how handling the
different 'event_selection*' events for
SymphonyTable and SymphonyTableCell could in general
be used to announce the current selection of multiple
cells.

It adds a method 'announce_selected_cells' to
SymphonyTable that just announces the names
of the first and last cell in the current selection
for now.

To avoid the same selection being announced multiple
times, the first and last cell of the last time
the method has been called is remembered and the
announcement is only done if the current selection
is different.
(The method may be called multiple times for the same
selection, since e.g. multiple SELECTION_ADD events
are triggerdd when multiple cells are added to a
selection at the same time.)

NOTES:

* This demo requires a current development version of
  LibreOffice to work.

* 'event_selectionRemove' is not triggered as expected,
  so the selection is not announced when removing cells
  from the selection using Shift+arrow keys.
  This looks like a problem on LibreOffice side.

* There are some other cases where events are not
  triggered as expeced on LO side, s.e.g.
  tdf#118508 [1] or tdf#18748 [2], which are
  also LibreOffice problems that need be handled there.

(Note: Strictly speaking, the change to
SymphonyTable::getSelectedItemsCount is unrelated, just makes
use of the newly added implementation of IAccessibleTable2.)
