Suggestion for template: sticky header

[spacevoyager78]

Hi! The header of the table contents can become sticky when scrolling, if you use:

#files.tablesorter thead tr th {
    position: sticky;
    top: 0;
}

Maybe you can consider putting it in the template. Support for position: sticky can be seen here: https://caniuse.com/css-sticky

Thanks for a great software!
