jquery datatables插件 表格数据初始化时，数据加载两次

/** 表格的数据渲染 /
function drawTable(aa001, aa002, aa003) {
dataTable = $("#dataTable").DataTable({
"searching": false,
"ordering": false,
"destroy": true,
"lengthMenu": [ 10, 20, 25, 30 ],

{ "data": "ab301"},

{ "data": "ab303"},

{ "data": "dc236"},

});
}

********console.log(data);********
return data.ab301;
}},

        { "data": "ab303"},
        { "data": "ac201"},
        { "data": "bm001"},
        { "data": "bm004"},
        { "data": "afk02"},
        { "data": "dc236"},
        { "data": "area"}
    ]
});

}

在console.log(data)时，控制台出现两遍加载的数据。是什么原因呢。

drawTable（aa001, aa002, aa003） 这个方法 你调用了几次？
