Cols Grammar

(What is this notation?)

Definitions:

columnSet: ColumnSet<*>

columnGroup: SingleColumn<DataRow<*>> | String| ColumnPath

column: ColumnAccessor| String| ColumnPath

index: Int

condition: ColumnFilter

T: Column type

indexRange: IntRange

What can be called directly in the Columns Selection DSL:

cols[<T>](column,.. | index,.. | indexRange)

| cols[ { condition} ]

| this/it [{ condition}]

| this/it [column,.. ]

What can be called on a ColumnSet:

columnSet

    .cols(index,.. | indexRange)

    | .cols[ { condition} ]

    | [{ condition}]

    | [index,.. | indexRange]`

What can be called on a Column Group (reference):

columnGroup

    .cols[<T>](column,.. | index,.. | indexRange)

    | .cols[ { condition} ]

    | [{ condition}]

    | [column,..]
