docs: 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
