some proposals of improvements for tables

[imendez]

Hi, I have some proposals of improvements for tables:

1.- A basic need is being able to execute formulas in cells.
2.- Now, when you click on a cell and write any text, this text is added to current text. I think that, as at most of programs, new text should substitute previous one.
3.- The headers (titles) of the columns can´t contain a "carry return" and it would be very useful.
4.- Now, it's possible to adjust the width of columns, but not the height of rows.
Also, it would be interesting adjusting automatically the width (height) of columns (rows) by clicking twice on the columns (rows) separator.
5.- Immobilizing columns and rows is essential, in order to see the index of a row (or a column) when the amount of columns (or rows) is high.

Regards.
