Alphabetical order

The alphabetical order only sort one column but do not sort the second.

For example I have entered this.

A C
B B
A A
A B
B C
B A

I highlight all and click the sort.
It will give me this.
A B
A A
A C
B B
B C
B A

The first column is sort, but the second column is not sort so I must sort again. But this waste so much time because I have so many rows.
