Excel Reference To Current Cell

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)

From stackoverflow

• A2 is already a relative reference and will change when you move the cell or copy the formula.

  GSerg : Don't worry about addressing style. All formulas use R1C1 internally anyway, it doesn't matter.

  Joey : Ah, thanks. Didn't bother to look it up right now (wading through the XML isn't exactly fun usually :))

• You could use

  =CELL("width", INDIRECT(ADDRESS(ROW(), COLUMN())))
  

  but Johannes's answer will work just as well

  GSerg : This makes the formula volatile. Therefore, provided there are non-volatile solutions, don't use this one.

• Leave off the second argument entirely, it is an optional argument. When you omit it, the function uses the host cell as the reference.

  =CELL("width")
