Making this table sortable Making this list sortable would add a lot of value by longitude by name by country launch date etc Unfortunately we can t simply apply the sortable attribute due to the hard coded subdivisions I recommend 1 moving the In Transit and Historical sections into separate table s 2 removing the hemisphere dividers and 3 converting the longitude Location to signed notation ie replace E W suffixes with values Making Location the default sort column would then result in the same hard coded order that the table currently has
