I have some problems to sort a large data table. In particular, I would like to sort a data table in such a way that the duplicated values in two columns are disposed one below the other and if possible in an ascending order (especially for the column "Date"). An example with a short data table and associated responses are showed in http://stackoverflow.com/questions/38879961/sort-a-data-table-with-specific-value-order) . However, the proposed solutions don't work with this data table. For example, the line 24 with the value 318880 for Tag1 is not below the line 8.
