使用 javascript 对数组表进行排序

Question

我正在做一个练习，我必须从 table 中读取数据并在数组中守卫以对序列进行排序：

有货，购买；
有货，无货；
已售出，正在购买；
已售出，无库存。

有人能帮我说说如何读取同一行的两个单元格然后在数组之间分配并生成一个新的 table 已经订购了吗？我的代码如下：

 <table id="giftreg-table" border="1" cellpadding="10" cellspacing="0" style="border-collapse:collapse;">
        <thead>
        <tr>
            <th>prod0</th>
            <th>sold</th>
            <th>Quantity</th>
        </tr>
        </thead>
        <tbody>

        <tr>
            <td>prod0</td>
            <td>available</td>
            <td>buy</td>
        </tr>
        <tr>
            <td>prod2</td>
            <td>sold</td>
            <td>buy</td>
        </tr>

        <tr>
            <td>prod2</td>
            <td>sold</td>
            <td>buy</td>
        </tr>

        <tr>
            <td>prod4</td>
            <td>available</td>
            <td>no Stock</td>
        </tr>
        <tr>
            <td>prod6</td>
            <td>available</td>
            <td>buy</td>
        </tr>

        <tr>
            <td>prod2</td>
            <td>sold</td>
            <td>buy</td>
        </tr>

        <tr>
            <td>prod5</td>
            <td>available</td>
            <td>buy</td>
        </tr>

        <tr>
            <td>prod3</td>
            <td>sold</td>
            <td>buy</td>

        <tr>

                }
                //NewTable();
                arrayNewTable[0] = arrayTitle;
                arrayNewTable[1] = arrayFirst;
                arrayNewTable[2] = arraySecond;

                    document.writeln(arrayNewTable[i]);
