This is a simple component to freeze the header of a table. 

Because a lot of them are just tricky to use, adapted this one because it is actually simple and makes the simple task of fixing the header of a table and also allows you to define the height of the table and makes it scrollable. 

See the original plugin link for more details:

Attention the script in this Widget is not the script from this source alone, some changes have been made to make it work properly. More specifically one of the changes reported on the Github has been fixed in this version of the component.
