在表格上绑定双层嵌套数组（数组操作中介绍的是三层嵌套数组）。

涉及知识点: 数组绑定 数组操作 文本内容绑定

1. 插入2行7列的表格，宽度设为100%，第一行设为表头，第一行填入数据如下图，第二行只保留第一个单元格。

2. 在tbody标签上进行数组绑定，绑定参数：monthdate；绑定变量初始化：

变量初始化中数据结构为双层嵌套数组，即数据最外层为数组，数组内的每一项也是数组。monthdate为外层数组名，代表是哪个月份；weekdate为外层数组内的每一项数组名，代表一个月内的第几周；date代表具体日期；disabled代表不是当月的日期样式，值为1表示不是当月日期，值为0表示是当月日期。

{"monthdate":[{"weekdate":[{"date":26,"disabled":1},{"date":27,"disabled":1},{"date":28,"disabled":1},{"date":29,"disabled":1},{"date":30,"disabled":1},{"date":31,"disabled":1},{"date":1,"disabled":0}]},{"weekdate":[{"date":2,"disabled":0},{"date":3,"disabled":0},{"date":4,"disabled":0},{"date":5,"disabled":0},{"date":6,"disabled":0},{"date":7,"disabled":0},{"date":8,"disabled":0}]},{"weekdate":[{"date":9,"disabled":0},{"date":10,"disabled":0},{"date":11,"disabled":0},{"date":12,"disabled":0},{"date":13,"disabled":0},{"date":14,"disabled":0},{"date":15,"disabled":0}]},{"weekdate":[{"date":16,"disabled":0},{"date":17,"disabled":0},{"date":18,"disabled":0},{"date":19,"disabled":0},{"date":20,"disabled":0},{"date":21,"disabled":0},{"date":22,"disabled":0}]},{"weekdate":[{"date":23,"disabled":0},{"date":24,"disabled":0},{"date":25,"disabled":0},{"date":26,"disabled":0},{"date":27,"disabled":0},{"date":28,"disabled":0},{"date":29,"disabled":0}]},{"weekdate":[{"date":30,"disabled":0},{"date":1,"disabled":1},{"date":2,"disabled":1},{"date":3,"disabled":1},{"date":4,"disabled":1},{"date":5,"disabled":1},{"date":6,"disabled":1}]}]}

3. 在单元格“日”下面单元格的tr标签上进行数组绑定，绑定参数：weekdate。

4. 在单元格“日”下面单元格中插入span标签，在span标签上进行文本内容绑定，绑定参数：date。

在span标签上进行CSS类绑定，绑定参数：{"disable":disabled}，diable表示不是当月的日期样式类名称。

在样式类文件中添加如下样式类：

.disable{
  color:#c3baba;
}
