Add one or more TR elements to the table. Generally we'd expect to
use this for reading data from a DOM sourced table, but it could be
used for an TR element. Note that if a TR is given, it is used (i.e.
it is not cloned).
 @param {object} settings dataTables settings object
 @param {array|node|jQuery} trs The TR element(s) to add to the table
 @returns {array} Array of indexes for the added rows
