Sorting, filtering, splitting, etc all take advantage of the index view of a table, which is simply a pointer to a Table along with a []int slice of indexes.

See: IdxView for all the methods.

ix := etable.NewIdxView(et) // new view with all rows

NewTable, SetTable

To "cache out" an index view into a Table that is physically organized in the order of the indexes, use the NewTable or SetTable methods.

Splits

Splits is a list (slice) of IdxView's, representing multiple different splits of table rows. See Splits.
