open fun String.takeCols(n: Int): ColumnSet<*>
open fun KProperty<*>.takeCols(n: Int): ColumnSet<*>
open fun ColumnPath.takeCols(n: Int): ColumnSet<*>
open fun SingleColumn<DataRow<*>>.takeCols(n: Int): ColumnSet<*>

This collects the first n columns from this into a ColumnSet.

open fun String.takeColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>
open fun KProperty<*>.takeColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>
open fun ColumnPath.takeColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>
open fun SingleColumn<DataRow<*>>.takeColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>

This operation takes the first columns from this while they adhere to the predicate, stops as soon as it encounters one that does not, and collects the taken columns into a ColumnSet.
