Steps to Reproduce: 1. Open LibreOffice Writer 2. Insert table of any size - for example 4x4 3. Enter some numbers in the table cells 4. Go to the last (right bottom) cell, hit "=", enter "=sum(<A1:D3>)" 5. Save the document as Microsoft Office DOC or DOCX and close document 6. Open just saved DOC/DOCX document and change some numbers in table (try pressing F9 for sure) Actual Results: * the formula in the table is not saved, the user is unable to calculate with it after saving file as DOC / DOCX Expected Results: * the formula in the table is saved, the user is able to calculate with it after saving file as DOC / DOCX Notes: the same happens if original document is DOC / DOCX. Saving table with formula removes the formula on next open. Test ODT document is in attachment.
