# Merge Columns

#### Task

Let’s say we have a table with user names in one column and their domains in the second column. Our task is to combine both columns to get a valid email list.

#### Decision

You have 2 alternatives to solve the task:

1. Using [`Concat()`](/data-transformation/formulas/string-functions/concat.md) function
2. Using operator [`|`](/data-transformation/formulas/what-are-formulas.md#operators)

#### Examples

```mathematica
Concat("Meeting on ", Today()) -> "Meeting on 2023-01-20"
"Alex" | " " | "Brown" -> "Alex Brown"
```
