worksheet function - Excel Reference To Current Cell

Question

How do I obtain a reference to the current cell?

For example, if I want to display the width of column A, I could use the following:

=CELL("width", A2)

However, I want the formula to be something like this:

=CELL("width", THIS_CELL)

Answer 1

Several years too late:

Just for completeness I want to give yet another answer:

First, go to Excel-Options -> Formulas and enable R1C1 references. Then use

  =CELL("width", RC)

RC always refers the current Row, current Column, i.e. "this cell".

Rick Teachey's solution is basically a tweak to make the same possible in A1 reference style (see also GSerg's comment to Joey's answer and note his comment to Patrick McDonald's answer).
