Improvement of tables

There's a few things that I think should be improved with tables:

1.

It should be easier to adjust the size of the table:

• When dragging right side of table increasing sizes of all colums in ratio to their size before resizing
• You should still be able to increase the size of columns by dragging the edges of the columns at the top

2.

As also mentioned in another ticket, you should be able to use the same commands in the table as in normal textfields like (+,>,|,etc.)

3.

To easily structure tables as it is possible in different editores you should be able to merge individual cells with each other to make a single header for example

I think there is already a similar ticket for that as well

I personally am still a little hesitant to use tables since I am strongly being limited in my ability to order and design my tables to be logically and asthetically pleasing and I think these 3 improvements would help a lot of people.
