| ---- | ------------------ | ---------------- | ------------- |
| john | + 1 (415) 691 9426 | 123 east street  | San Francisco |

Note: This sample table can be generated using the `create a sample table` procedure.

{% tabs %}
{% tab title="Automation" %}

```
get the column's column number
```

{% endtab %}

{% tab title="Results" %}
2
{% endtab %}
{% endtabs %}

Since the columns are numbered starting at 0, the `Address` column has a column number (index) of 2.
