I need some help creating a macro in MS Excel.

Say I have a worksheet with 20+ columns of various column
widths. All I need is to get the size of each column and
put it in a cell of the respective column.

If the cursor was placed on a row where the column
headings are available, I want the macro,

to get width of respective column and save it in the next
row
go to next column and do step 1
stop when no more columns are available (say it reaches
the empty cell)


After executing the macro, the Worksheet should look
something like this:

A B C D E
Name ID DOB Comment
15.14 8.43 11.14 25

Thanks in Advance for the help.
