$(document).ready(function () {
    $('#tblAH1').after('<div id="pager" style="" ></div>');
    var rowsShown = 5;
    var rowsTotal = $('#tblAH1 tbody tr').length;
    var numPages = rowsTotal / rowsShown;
    for (i = 0; i < numPages; i++) {
        var pageNum = i + 1;
        $('#pager').append('<a href="#" rel="' + i + '">' + pageNum + '</a> ');
    }
    $('#tblAH1 tbody tr').hide();
    $('#tblAH1 tbody tr').slice(0, rowsShown).show();
    $('#pager a:first').addClass('active');
    $('#pager a').bind('click', function () {

        $('#pager a').removeClass('active');
        $(this).addClass('active');
        var currPage = $(this).attr('rel');
        var startItem = currPage * rowsShown;
        var endItem = startItem + rowsShown;
        $('#tblAH1 tbody tr').css('opacity', '0.0').hide().slice(startItem, endItem).
        css('display', 'table-row').animate({ opacity: 1 }, 300);
        event.preventDefault();
