Sort by numeric values

[fiegam]

When data are provided as a table, sorting by numeric column returns data in incorrect order. This is caused by invalid sorting conditions in the _refreshData function:

if ($.isNumeric(aVal)) {
      if (aVal < bVal) {
              return 1;
      } else if (aVal > bVal) {
              return -1;
      }
      return 0;
}

Thanks for reporting this - I'll take a look shortly.
