code: protected Locator byIdSuffix(String suffix) {
          if (tableId == null) {
              tableId = innerTable.getAttribute("id");

docs: Many elements within the wrapper div have ids in the format, ${table's_id}_${suffix}. This
  itself is a locator strategy, implemented by this method. The returned locator can be used
  by itself to find one of these elements. It does not need to be nested inside of
  {@link #byInner(com.redhat.darcy.ui.api.Locator, com.redhat.darcy.ui.api.Locator...)} (it is
  already).
  
  @param suffix The suffix to append after the inner table's id, plus an _, in the format,
  ${table's_id}_${suffix}.
