Table-multiple-sort in boostrap-table doesn't work for multiple tables in one page

Question

I use bootstrap-table and extension table-multiple-sort. When I have two tables in one page (in my case second table is in modal window), in second table I don't have any choice for multisorting.

jsfiddle

html

<table ref="mainTable" className="table table-striped table-bordered table-hover" cellSpacing="0" id="mainTable" data-show-toggle="true" data-show-columns="true" data-search="true" data-pagination="true">
             <thead>
                <tr>
                   <th data-field="state" data-checkbox="true"></th>
                   <th data-field="Customer Name" data-halign="center"
                      data-align="left" data-sortable="true">Customer Name</th>
                   <th data-field="Location Type" data-halign="center"
                      data-align="left" data-sortable="true">Location Type</th>
                   <th data-field="Location" data-halign="center"
                      data-align="left" data-sortable="true">Location</th>

Answer 1

Your modal table headers are missing the data-sortable="true" attribute:

<thead>
    <tr>
        <th data-field="state" data-checkbox="true"></th>
        <th data-field="Customer Name" data-halign="center"
            data-align="left" data-sortable="true">Customer Name</th>
        <th data-field="Location Type" data-halign="center"
            data-align="left" data-sortable="true">Location Type</th>
        <th data-field="Location" data-halign="center"
            data-align="left" data-sortable="true">Location</th>
    </tr>
</thead>
