Description
I've tried to use https://github.com/mjpclab/jquery-table-fixed-header in order to make table header rows fixed while scrolling. Unfortunately there seems to be something in the Hugo Learn Theme causing the fixed table header rows to be wider than the original table header.

I've failed to understand exactly what causes this behaviour. In all other examples not using Hugo I've tried, this problem does not exist.
Would be great if Hugo Theme Learn could include support for fixed table headers, either by solving any issues with https://github.com/mjpclab/jquery-table-fixed-header or by any other means.
