Q: How do I create sortable tables?

Answer

Use the /{table-plus/} macro. You simply put one on each side of a table to make it a sortable table. Then users can click on the column headers to sort the table. Here's an example of how the wiki markup looks:

{table-plus}
||Names||Numbers||Letters||Animals||
|Jane|1|D|Dog|
|Bob|2|C|Cat|
|Anne|3|B|Hedgehog|
|Joe|4|A|Cat|
{table-plus}

You can see how the table looks rendered here:
