more cells in a table field

[-= JB =-]

Here are a few more questions about a table field;

1.  If you click on a line you can get the number of line clicked.
Question:  can you get the item(cell) clicked?

2.  If you enter text in line 4 item 2 and then leave the item by
going to another line, item or leave the field can you detect
which line and item you last altered.

2.  How do you resize a column?
Is it possible for the user to click on the column divider and resize  
it?
Can you resize a column by script?

thanks,
