I know this looks like an idiotic questions. But I need to know. Before shifting to Ubuntu in Microsoft word theres a eraser button in doc menu which I used several times. But in Ubuntu libreoffice I can't find anything like it. Is it exist in it? Or I have to use another one which have this button. Then please suggest me another program.

In LibreOffice Writer in its Table Toolbar there is a merge-button.
If I understand it well, that's what the eraser button in ms word is supposed to do do.: erase the cell border, so that the cells are merged.
(I don't use ms word, so I can be wrong.)
