vue2.x+iview实现可编辑表格

1.首先看下效果图：

2.关键代码：

tbColumns: [ //主要是render不一样
        {
          title: "姓名",
          key: "name",
          render: (h, params) => {

                      value: params.row.name,
                  },
                  attrs: {
                      id: `name_${params.index}`
                  },
                  on: {
                      "on-blur": () => {
                        this.tbDataCopy[params.index].name = document.querySelector(`#name_${params.index} input`).value;
                      }
                  }
              });
            } else {

主要仍是依据了数据驱动视图，在每一个表格行数据中添加"edit"来标识当前行的编辑状态。再加上render函数可渲染iview中的组件，大部分api也是可用的(v-model无效)，因此实现可编辑表格仍是ok的，这里也算是做为一个参考的例子。若有其余方案或可改进之处还望指出。
