el-table el-column selection disable

几个要点：

1.通过 selectable 绑定

2.绑定的方法只能返回0/1

               <el-table-column
                    type="selection"
                    width="55"
                    :selectable="checkbox_select">
                </el-table-column>

           checkbox_select(row, index){
                if (this.$MyComm.isEmpty(row.bug_id)){
                    return 0
                }else {
                    return 1
                }
