I need to create an ascending sort across multiple columns

Hello all!

I have multiple columns of data - varying number of columns each with varying numbers of rows. If the 1st number in column A fits between the 3rd and 4th numbers in column B, I want to move the one in column A down to the proper position and move the numbers in column B that fit AFTER the one in column a to move down, leaving a blank where the number in column A now resides. This needs to continue across however many columns are in a particular sheet and down as many rows as the data takes up.

Also, if possible, I'd like to insert 2 columns at the left side of the sheet and have the "new" column A show a list of the unique number in that row.

I'm thinking that I need to start by sorting each column, indiviually, in numeric order.

Often the sheet I'm working on is 15-20 columns and many rows long, so it's REALLY hard to eye-ball this correctly.

I know that I don't explain well in words, so I'll attach a workbook showing my original data on Sheet1 and my desired result on Sheet2.

Any help would be greatly appreciated!
