# How to combine tables horizontally in Parabola (without matching data)

> Sometimes you may want to **combine two tables side-by-side** (horizontally), even though they don't share a matching key column. Parabola's Combine tables step typically requires a shared value to match on — but here's a workaround:

## Step-by-Step Instructions

<Steps>
  <Step title="Add a constant column to each table">
    * After each of your two input tables, add an **Add text column** step.
    * In each step:
      * Create a new column called `Merge`
      * Set the column value to a constant like `Join` (same value for both tables)
  </Step>

  <Step title="Combine the tables using the Merge key">
    * Drag in a **Combine tables** step.
    * Connect both of your updated tables to it.
    * In the Combine settings:
      * Set **"Keep all rows"** for both tables.
      * In the **Columns to match** section, choose the `Merge` column from each table.
      * Click **Update results**
  </Step>

  <Step title="Remove the temporary Merge column">
    * Use an **Edit columns** step after the Combine tables step.
    * Choose **"Remove these columns"** from the dropdown.
    * Select the `Merge` column to remove it.
  </Step>
</Steps>

## Final Result

Your two tables will now be **combined horizontally**, with rows aligned by the artificial `Merge` key. This works best when:

* Each table only has one row (e.g., summary data), or
* You want to force a horizontal join regardless of row count.
