# Conditional formatting last n rows

To highlight the last n rows of a range or a table, you can use a formula based on the ROW and ROWS function. In the example shown, the formula used to apply conditional formatting to the data in B5:D15 is:

where **data** (B5:D15) and **n** (F5) are named ranges. This rule highlights the last n rows in the data. When n is changed, the highlighting is automatically updated.

This example is based on the formula explained in detail here:

The formula uses the greater than operator (>) to check row in the data. On the left, the formula calculates a "current row", normalized to begin at the number 1:

On the right, the formula generates a threshold number:

ROWS(data)-n // calculate threshold

When the current row is greater than the threshold, the formula returns TRUE, triggering the conditional formatting.

### Conditional formatting rule

The conditional formatting rule is set up to use a formula like this:

### With a table

You can't use a table name in a CF formula at present. However, you can select or enter the table data range when creating the formula in the CF window, and Excel will keep the reference up to date as the table expands or shrinks.
