php与前端（二）：页面table的单元格的数据add和update

适合场景是修改的时候不跳页面，也不弹模态框，这么刁钻能实现吗？能，直接在，单元格内写表单修改，样式如下图

1：html代码部分
包括要修改的html和新增的html

<table id="btnShow" class="table table-bordered table-hover"  >
    <thead>
        <tr>
            <th>行类型</th>
            <th>排序</th>
            <th>表达式描述</th>
            <th>操作</th>
        </tr>
    </thead>
    <tbody>
        <volist name="rowArr" id="list">
            <tr>
                <td>
                    <select  name="row_type-{$list.row_id}_{$list.tpl_id}" >
                        <option value="1" <?php echo $list['row_type']==1 ? 'selected' : '' ?> >一维数据</option>
                        <option value="2" <?php echo $list['row_type']==2 ? 'selected' : '' ?> >二维数据</option>
                    </select>
                </td>
                <td>
                    <input type="text" class="listorder" name="row_sort-{$list.row_id}_{$list.tpl_id}" value="{$list.row_sort}" >

                </td>
                <td>
                    <button type="button" rel="{$list.row_id}_{$list.tpl_id}" class="button " data-target="btn-save">

                    </button>
                    <a href="__CONTROLLER__/cellList/tplId/{$list.tpl_id}/rowId/{$list.row_id}">
                        <button type="button" rel="{$list.row_id}_{$list.tpl_id}" class="button" data-target="btn-edit">
                            单元格
                        </button>
                    </a>
                </td>
            </tr>
        </volist>
        <!--新增部分html-->
        <tr>
            <td>
                <select name="row_type" >
                    <option value="1">一维数据</option>
                    <option value="2">二维数据</option>
                </select>
            </td>
            <td ><input type="text" name="row_sort" value="0" ></td>
            <td>
                <textarea name="desc-{$list.row_id}_{$list.tpl_id}"></textarea>
            </td>
            <td>
                <button type="button" class="button" data-target="btn-save" isadd="true">
                    确定新增
                </button>
            </td>
        </tr>
