Question

我需要在我的项目中实现数据表。我想在表格底部显示总数，如下所示：

我已经制作了这样的默认数据表：

这是我的代码。

<?php
    include "db.php";
    $obj->tglan=$obj->get_hari();
    if (isset($_POST['tanggal2'])) {
        $obj->tglan = $_POST['tanggal2'];

    }
?>

我已经搜索了，但很少有参考，但我无法理解如何添加Total cell并显示在datatable的底部？

请参阅此示例此处由bindrid编写的http://jsbin.com/putiyep/edit?js,output。

基本上它利用API的footerCallback并使用表的列索引和基本数学来返回总数。

代码摘录（同样不是我的代码）：

// Table definition
var dtapi = $('#example').DataTable({
    data: dataSet,
    pageLength: 3,
    "deferRender": false,
    "footerCallback": function (tfoot, data, start, end, display) {
        var api = this.api();
        var p = api.column(4).data().reduce(function (a, b) {
            return a + b;
        }, 0)
        $(api.column(4).footer()).html(p);
        $("#total").val(p);
    },
    "order": [1],
    "columns": [

        // rest of the columns
        { data: "first_name" },
        { data: "last_name" },
        { data: "firstNumber" },
        {
            data: "secondNumber", render: function (data) {
                return '<input type="text" style="width:50px" value="' + data + '">';
            }
        },
        { data: "rowTotal" }

    ]
});
