# Auto Row Numbers

> Automatically add sequential row numbers to line item tables

DocsAutomator enables you to automatically add row numbers to line item tables with minimal configuration.

## Basic Setup

Under line item settings, locate the option to enable auto row numbers for your line item table. Once activated, the system will automatically number each row sequentially.

## Configuration Options

### Style Settings

Access styling controls via the settings/gear icon adjacent to the auto number toggle.

| Option       | Description                     | Default |
| ------------ | ------------------------------- | ------- |
| Column Width | Adjustable range from 10 to 100 | 25      |
| Alignment    | Left, Center, or Right          | Left    |

## Example Output

| # | Description | Quantity | Price   |
| - | ----------- | -------- | ------- |
| 1 | Widget A    | 2        | \$10.00 |
| 2 | Widget B    | 1        | \$25.00 |
| 3 | Widget C    | 3        | \$15.00 |

## Hierarchical Numbering

When using [Nested Line Items](/features/line-items/nested-line-items), auto row numbers generate hierarchical numbers:

| #     | Item           |
| ----- | -------------- |
| 1     | Parent Item A  |
| 1.1   | Child Item A1  |
| 1.1.1 | Grandchild A1a |
| 1.2   | Child Item A2  |
| 2     | Parent Item B  |
| 2.1   | Child Item B1  |

## Data Ordering

<Info>
  When using Airtable as your data source, row sequence can be controlled through a specified view configuration. Reference the [Airtable integration documentation](/integrations-api/airtable) for ordering details.
