Sorting Multiple Columns

How do I sort multiple columns at once? In other words, I have a chart that is a series of 1s and 2s, and I need all of the 1s to drop to the bottom, so that I can do a rudimentary chart in spreadsheet form. My chart has dozens of columns like so:

1 2 1 1 1 2 2 2 2
1 2 1 1 2 1 1 2 2
2 1 2 2 2 2 2 2 2
1 1 1 2 1 1 1 1 2

How do I get the entire range sorted to look like this, without having to do each column individually (hours of work)?:

2 2 2 2 2 2 2 2 2
1 2 1 2 2 2 2 2 2
1 1 1 1 1 1 1 2 2
1 1 1 1 1 1 1 1 2
