vue+element UI实现树形表格
一：在component文件夹下新建如下treeTable文件夹，里面有2个文件：
eval.js:将数据转换成树形数据
/**

*/
'use strict'
import Vue from 'vue'
export default function treeToArray(data, expandAll, parent = null, level = null) {
let tmp = []
Array.from(data).forEach(function(record) {
if (record._expanded === undefined) {
Vue.set(record, '_expanded', expandAll)
}
let _level = 1
if (level !== undefined && level !== null) {
_level = level + 1
}
Vue.set(record, '_level', _level)
// 如果有父元素
if (parent) {
Vue.set(record, 'parent', parent)
}
tmp.push(record)
if (record.children && record.children.length > 0) {
const children = treeToArray(record.children, expandAll, record, _level)
tmp = tmp.concat(children)
}
})
return tmp
}
index.vue:树形表格组件
{{ scope.$index }}
{{ scope.row[column.value] }}
二：在需要的地方引入该组件：
例如：在component文件夹下新建a.vue:
import treeTable from "./TreeTable";
components: { treeTable },
data() {
return {
columns: [
{
text: "事件",
value: "event",
width: 200
},
{
text: "ID",
value: "id"
},
{
text: "时间线",
value: "timeLine"
},
{
text: "备注",
value: "comment"
}
],
data: [
{
id: 0,
event: "事件1",
timeLine: 50,
comment: "无"
},
{
id: 1,
event: "事件1",
timeLine: 100,
comment: "无",
children: [
{
id: 2,
event: "事件2",
timeLine: 10,
comment: "无"
},
{
id: 3,
event: "事件3",
timeLine: 90,
comment: "无",
children: [
{
id: 4,
event: "事件4",
timeLine: 5,
comment: "无"
},
{
id: 5,
event: "事件5",
timeLine: 10,
comment: "无"
},
{
id: 6,
event: "事件6",
timeLine: 75,
comment: "无",
children: [
{
id: 7,
event: "事件7",
timeLine: 50,
comment: "无",
children: [
{
id: 71,
event: "事件71",
timeLine: 25,
comment: "xx"
},
{
id: 72,
event: "事件72",
timeLine: 5,
comment: "xx"
},
{
id: 73,
event: "事件73",
timeLine: 20,
comment: "xx"
}
]
},
{
id: 8,
event: "事件8",
timeLine: 25,
comment: "无"
}
]
}
]
}
]
}
]
};
},
这样就大工告成了
