Tables

 To open a new table, click in the menu Tables->Open Table or Tables->Open a ruled Table, this starts a new table. To create a new cell for the table, use the Escape key.
    To end the first line of the table just use twice the Escape key. The number of columns is now fixed !
    To leave the table use either the mouse to click elsewhere or the Tables->Close Table command.
   A table is made of cells and in a cell you can put exclusively a line of text with formulas or another table.
    To put another table just click on Tables->Open Table or Tables->Open a ruled Table.
    For instance to put two lines of text in a cell, open a table in the (empty !) cell and type the first line, then two times hit
Escape, then type your second line of text.
     If you are in a table already in previous cell, to go back to the
previous cell use the Up key then, if you want to add a new cell to the previous table hit the Escape key.
    To delete a cell, clic just before its end of line mark (a grey diamond) and delete it.

In a table, a right click  shows a pop-up menu for pushing left or right the content of the cell. Or to separate the content of the cell.
