# Table (/workflows/triggers/table)





The **Table trigger** reacts to committed row inserts, updates, or deletes in a [Sim table](/tables). For example, start enrichment when a row is added or send a notification when a watched status changes.

<BlockPreview type="table_v2" />

## Configuration [#configuration]

1. Select **Table**, or enter **Table ID** in advanced mode. Choose a table in the workflow's workspace.
2. Choose **Event**: **Row Inserted**, **Row Updated**, or **Row Deleted**. The default is Row Inserted.
3. For updates, optionally select **Watch Columns**. Leave it empty to react to any update.
4. Choose **Map Row Values to Headers**, on by default, then connect the downstream blocks.
5. Deploy the workflow and make the corresponding row change. Verify the run in [Logs](/logs-debugging).

One trigger watches one event type. Use separate trigger blocks to handle several event types.

## Outputs [#outputs]

These examples use a trigger named Table:

| Reference | Value |
| - | - |
| `<table.row>` | Name-keyed row with missing schema columns filled, when header mapping is on; otherwise `null` |
| `<table.rawRow>` | Row values projected to column names, including select option names |
| `<table.previousRow>` | Previous row for an update, deleted row data for a delete, or `null` for an insert |
| `<table.changedColumns>` | Changed column names for an update; empty for inserts and deletes |
| `<table.rowId>` | Row ID |
| `<table.headers>` | Table column names |
| `<table.tableId>` | Table ID |
| `<table.tableName>` | Table name |
| `<table.timestamp>` | Event time in ISO format |

Watch Columns applies only to updates. If none of the watched columns changed, that update does not start a run.

## Delivery behavior [#delivery-behavior]

Table events fire directly after the row mutation rather than waiting for a poll. Workflow dispatch is fire-and-forget: a workflow failure does not undo the committed table change. Runs use the deployed trigger configuration, so deploy an update after changing its event or watched columns.
