Selector in tableview counted as value column

[isbm]

The following will return an empty value:

attributes:
  - selector
  - value = 1

Selector column is also included into the result.

NOTE: this works correctly when hidden column is present, e.g. this will return "c" as expected:

attributes:
  - selector
  - hidden,value = 3
options:
  - ["some", "header", "value"]
  - ["a", "b", "c"]
