  Vertical lookup. Searches the given table for a record matching the given `field=value`
  arguments. If multiple records match, returns one of them. If none match, returns the special
  empty record.

  The returned object is a record whose fields are available using `.field` syntax. For example,
  `VLOOKUP(Employees, EmployeeID=$EmpID).Salary`.

  Note that `VLOOKUP` isn't commonly needed in Grist, since [Reference columns](col-refs.md) are the
  best way to link data between tables, and allow simple efficient usage such as `$Person.Age`.

  `VLOOKUP` is exactly quivalent to `table.lookupOne(**field_value_pairs)`. See
  [lookupOne](#lookupone).

  For example:
  ```
  VLOOKUP(People, First_Name="Lewis", Last_Name="Carroll")
  VLOOKUP(People, First_Name="Lewis", Last_Name="Carroll").Age
  ```
