How do i properly configure this element type?

Given
Table with two columns: “column_name” & “column_label”

Expected result
An element with the name xxxx. This element is a drop down menu which shows the values from the column “column_label” and takes the values for the column “column_name”.

Bonus question
Which syntax would i have to use to display the plain result as a title of table element

[...]
"$title": {
"value": "{{xxxx}}"
}

I believe data select is the wrong element for this usecase.
With variableConfigSingleSelect you can select values from a column and store them in a variable which then can be used as, e.g., a title.

"id": "select",
  "type": "variableConfigSingleSelect",
  "source": "dataSource",
  "config": {
    "variable": "selectValue",
    "options": [
      {
        "origin": "data",
        "id": "vals1", // the id for the value set can be arbitrary
        "valueColumn": "column_name",
        "labelColumn": "column_label"
      }
    ]
  }
}

the title then be assigned the selected value with

"$title": {
      "type": "string",
      "value": "{{selectValue}}"
    },

Thank You for the hint Tim.
I do actually need to retrieve a set of rows from the underlying data source. As i understand from the Documentation variableConfigSingleSelect only allows for a single selection.
