Missing bootstrap table Icons

I'm using Bootstrap and Bootstrap-table, but can't get the icons to show. I've double checked to make sure that my versions are correct, however regardless the icons for print, sort etc are not showing at the top of the table. When I copy the code into the bootstrap-table online editor, the multi sort shows but not the other buttons. This phenomenon is platform independent (occurs in chrome, firefox and safari).

The Problem (Notice the lack of icons)

And my Script section

    var $table = $('#varTable');
    $(function() {

        var varData = [{'basic.row.na':"1",'basic.source.na':"HGMD",'basic.gene.na':"EXO5",'basic.chr.na':"1",'basic.pos.na':"40514996",'basic.ref.na':"T",'basic.alt.na':"C",'basic.trans.na':"NM_001346946.1",'basic.hgvsc.na':"NM_001346946.1:c.452T>C",'basic.hgvsp.na':"NP_001333875.1:p.Leu151Pro",'bio.type.na':"snp: ts",'bio.biotype.na':"protein_coding",'bio.impact.na':".",'bio.aachange.na':"L/P"},{'basic.row.na':"2",'basic.source.na':"HGMD;CLINVAR",'basic.gene.na':"FLG",'basic.chr.na':"1",'basic.pos.na':"152313385",'basic.ref.na':"G",'basic.alt.na':"A",'basic.trans.na':"NM_002016.2",'basic.hgvsc.na':"NM_002016.2:c.1501C>T",'basic.hgvsp.na':"NP_002007.1:p.Arg501Ter",'bio.type.na':"snp: ts",'bio.biotype.na':"protein_coding",'bio.impact.na':".",'bio.aachange.na':"R/*"},{'basic.row.na':"3",'basic.source.na':"HGMD",'basic.gene.na':"SMPD1",'basic.chr.na':"11",'basic.pos.na':"6390704",'basic.ref.na':"T",'basic.alt.na':".",'basic.trans.na':"NM_000543.5",'basic.hgvsc.na':"NM_000543.5:c.138_143del",'basic.hgvsp.na':"NP_000534.3:p.Ala48_Leu49del",'bio.type.na':"indel: del",'bio.biotype.na':"protein_coding",'bio.impact.na':".",'bio.aachange.na':"VLA/V"}];

        $table.bootstrapTable({ data: varData });
    });
</script>

Solution

I was dealing with this exact issue. In my case i was missing the link to fontawesome where they are pulling the icons:

link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css"
