Bootstrap-table-export: icon not showing

I'm using bootstrap-table-export to be able to export data from a table, but the icon is weird:

Does anyone knows how to change this icon? I read the docs, but I didn't understand it.

Solution

The icon is a glyphicon. If you got this symbol instead of the normal glyphicon-export, you should check if you are including the bootstrap correctly. The recommended CDN for Bootstrap is:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

Hope it helps.
