# Tables as Inputs & Outputs

It is possible to use tables as inputs and outputs through Mapper. There are some restrictions and details that might be a little different than your usual table, but mainly it is as easy as selecting a range and adding it through the Mapper.

1. Navigate to the **Mapper** application.
2. Select a range that consists of multiple cells. Make sure that the top left cell of your selection is not empty. Otherwise, the mapper won't detect your selection.
3. Click on **Add Selected** to add your input/output.

{% hint style="info" %}
Table inputs and outputs automatically get the address of the range as their name, you can change this through the taskpane or the Name Manager.
{% endhint %}

### What separates table input from table output

The mapper automatically determines whether a range is input or output by checking the bottom-right cell of the selection. Note that, you can always move inputs and outputs up and down to change an input to an output, or vice versa.
