Hi Russell,

You can definitely apply a filter down a column in Excel. Here's how:

1. Select the entire table or range of data that you want to filter.
2. Go to the Data tab in the ribbon at the top of the screen.
3. Click on the Filter button. This will add drop-down arrows to the headers of each column in your table.
4. Click on the drop-down arrow for the column you want to filter.
5. Select the criteria you want to filter by. You can choose from options like "equals", "does not equal", "contains", "begins with", etc.
6. Click "OK" to apply the filter.

You can also apply multiple filters at once by clicking on the drop-down arrows for multiple columns and selecting criteria for each one.
