# Delete Column In Data Table Step

The Delete Column In Data Table step takes a column out of an existing Data Table variable. Use this step to clean up data tables by getting rid of columns you don't need.

## How to Use Delete Column In Data Table

Use this step to remove a column from a Data Table. You can pick the column by its name or its number.

### Step 1: Add the Delete Column In Data Table Step

1.  Drag and drop the **Delete Column In Data Table** step into your process.

### Step 2: Set Up Input Parameters

1.  In the step properties, type the **DataTable name**. This is the name of the Data Table variable you want to change.

Choose how to find the column to delete:

-   Type the **Column name** (like `"Email Address"`) if you know the column's title.

Type the **Column index** (like `2` for the third column) if you know its number.

**Important:** You need to give either a Column name or a Column index, but not both.

### Step 3: Set Up Output Parameters

1.  For **Result DataTable**, give a variable name. This variable will hold the Data Table after the column is gone. You can use a Data Table variable you already have or make a new one.
2.  For **Column count**, give a variable name. This number variable will hold how many columns are left in the Data Table after the deletion.

## Parameters Explained

**Step name** (Optional)

-   A custom name for the process step. This helps you find the step in your workflow.

**DataTable name** (Required)

-   The name of the Data Table variable you want to change.
-   Example: `myDataTable`

**Column name** (Required if 'Column index' is empty)

-   The name of the column you want to remove.
-   Example: `"Old Data Column"`
-   Use this when you know the column's title.

**Column index** (Required if 'Column name' is empty)

-   The number for the column you want to remove. Columns start counting at `0`, so the first column is `0`, the second is `1`, and so on.
-   Example: `3`
-   Use this when you know where the column is.

**Result DataTable** (Required)

-   The variable that will hold the Data Table after the chosen column is removed.
-   Example: `updatedDataTable`
-   This output variable has the changed Data Table.

**Column count** (Required)

-   A number variable that will hold how many columns are in the `Result DataTable`.
-   Example: `remainingColumnCount`
-   This tells you how many columns are left after the action.
