<table class="table-striped table-hasthead" id="tableTest1" data-search="true">
    <thead>
        <tr>
            <th data-sortable="true" data-field="id">Id</th>
            <th data-field="name">Name</th>
            <th data-sortable="true" data-field="url">Website</th>

            <th data-field="country">Country</th>
        </tr>
    </thead>
</table>

    $(function() {
        var url = "selectBtTable.php?action=init_data_list";
        $('#tableTest1').bootstrapTable({
            height: $(window).height() - 460,
            url: url
        });
        setInterval(refreshData, 3000)
        function refreshData() {
            var scollPostion = $('#tableTest1').bootstrapTable('getScrollPosition');
            $('#tableTest1').bootstrapTable('refresh', { silent: true, url: "selectBtTable.php?action=init_data_list" });
            setTimeout(function() {
                $('#tableTest1').bootstrapTable('scrollTo', scollPostion);
            }, 60);
        }
        $(window).resize(function() {
            $('#tableTest1').bootstrapTable('resetView');
        });
    });
