# Linked rows

Linked rows use regular tables.
When you create a table for case-linked evidence, use the same `columns` JSON schema documented in [Tables](/automations/tables) and [Table actions](/automations/core-actions/memory-actions/tables).

## `core.cases.link_row`

Link an existing table row to a case.

### Inputs

<ParamField path="case_id" type="string" required>
  Case ID
</ParamField>

<ParamField path="row_id" type="string" required>
  Row ID
</ParamField>

<ParamField path="table_id" type="string" required>
  Table ID
</ParamField>
