+The **Merge** operation combines two input `Table` objects by matching rows that share the same value in a selected column.
+For example, if one table has `id` and `name`, and another has `id` and `department`, you can merge both tables on `id` to produce one table with `id`, `name`, and `department`.

+Provide the following parameters:

+* **Left Table** (`left_dataframe`): The primary table in the merge.
+* **Right Table** (`right_dataframe`): The secondary table in the merge.
+* **Merge On Column** (`merge_on_column`): The shared column used to match rows. This column must exist in both tables.
+* **Merge Type** (`merge_how`): Controls which matched and unmatched rows are kept in the output. Use `inner` to keep only matching rows, `left` to keep all rows from the left table, `right` to keep all rows from the right table, or `outer` to keep all rows from both tables.
