The Table.cellSet()
iteration order of the provided table
determines the iteration ordering of all views in the returned table. Note
that some views of the original table and the copied table may have
different iteration orders. For more control over the ordering, create a
ImmutableTable.Builder
and call ImmutableTable.Builder.orderRowsBy(java.util.Comparator<? super R>)
,
ImmutableTable.Builder.orderColumnsBy(java.util.Comparator<? super C>)
, and ImmutableTable.Builder.putAll(com.google.common.collect.Table<? extends R, ? extends C, ? extends V>)
Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.
