Hi, Lucy

You don’t need to install DataTables as well because TablePress has done it for you.

The extension works just like a normal WordPress plugin, so install it like you install TablePress and it’ll work.

But the usage is a little different. For this extension only, you just need to change the ShortCode (like [table id=123 /]) to others, like:

[table id=123 datatables_columnfilterwidgets=true /]

The string datatables_columnfilterwidgets=true means you’ve using this extension.

And if you use the following ShortCode,
[table id=123 datatables_columnfilterwidgets=true datatables_columnfilterwidgets_exclude_columns=2,3,4 /]
The TablePress table with id number 123 will be datatables_columnfilterwidgets enabled, and all the columns will get the effect, except for column 2,3,4.

I’m not sure whether I understand completely. Does “categories” means the name of the four lists on the live demo page?

As you can see from the demo table, the NAME of each dropdown list is exactly the content of the corresponding cell in the head row of the table. That is name of column.

If that’s what you mean, you could just put category names in the first row of the table, then scroll down to “Table Options” section in this table’s EDIT screen and tick on the “Table Head Row: The first row of the table is the table header.”
