In LibreOffice or OpenOffice Writer, editing a text document, I can create a table and add a formula to a table cell by entering an equal sign. However, I cannot find a way to view and re-edit the formula once it's been entered.
LibreOffice help only explains how to enter a formula, but doesn't mention viewing or re-editing it.
How to view and re-edit formulas?
The LibreOffice help isn't precise enough at this point. You can do it by selecting the table cell with your formula and then press F2.
To do a test I created a 3x3 table in LO Writer, typed = sqrt 9
in the first cell and pressed Enter. Now a 3
appears in this cell. By pressing F2 the formula bar is shown up and I can do my edit (see selection).
