Ant design Vue 去除展开按钮与自定义按钮触发行展开
作者:互联网
<template>
<a-table
:columns="columns"
:data-source="data"
:expandIconColumnIndex="-1"
:expandIconAsCell="false"
:rowKey="(record) => record.key"
:expandedRowKeys="curExpandedRowKeys"
:row-selection="{
selectedRowKeys: selectedRowKeys,
onChange: onSelectChange,
}"
>
<!--
columns //表格标题
data-source //表格数据
expandIconAsCell={false} // 去除表格标题栏+号(如果需要前面的加号可以不需要添加,我的需求是自定义展开所以要隐藏!!!)
expandIconColumnIndex={-1} // 去除表格body里的+号(如果需要前面的加号可以不需要添加,我的需求是自定义展开所以要隐藏!!!)
rowKey //一定要是唯一值不然会报错
expandedRowKeys //这个属性很重要决定哪行展开!!!
row-selection //列表项是否可选择
-->
<a slot="action" slot-scope="record" @click="handleExpand(record.key)"
>点我展开</a
>
<p
slot="expandedRowRender"
slot-scope="record"
style="margin: 0; height: 200px; background: #ccc"
>
我是被展开的行
</p>
</a-table>
</template>
<script>
const columns = [
{ title: "Name", dataIndex: "name", key: "name" },
{ title: "Age", dataIndex: "age", key: "age" },
{ title: "Address", dataIndex: "address", key: "address" },
{
title: "Action",
dataIndex: "",
key: "x",
scopedSlots: { customRender: "action" },
},
];
const data = [
{
key: 1,
name: "John Brown",
age: 32,
address: "New York No. 1 Lake Park",
description:
"My name is John Brown, I am 32 years old, living in New York No. 1 Lake Park.",
},
{
key: 2,
name: "Jim Green",
age: 42,
address: "London No. 1 Lake Park",
description:
"My name is Jim Green, I am 42 years old, living in London No. 1 Lake Park.",
},
{
key: 3,
name: "Joe Black",
age: 32,
address: "Sidney No. 1 Lake Park",
description:
"My name is Joe Black, I am 32 years old, living in Sidney No. 1 Lake Park.",
},
];
export default {
data() {
return {
data,
columns,
curExpandedRowKeys: [], //点击哪行展开数组(数组里只会存在一个值,具体逻辑在methods的点击事件里.)!!!
selectedRowKeys: [],//列表项是否可选择数组
};
},
methods: {
//点击展开逻辑,这里的行处理的核心逻辑是:每次只允许展开表格中的某一行。具体如下:当点击某行按钮时,
//将当前行数据的 key 传递到点击函数中,并在判断当前点击行是否在绑定数组中存在。若存在,则需要判断点击行是否是已展开行。
//若是已展开行,则将其关闭,否则,即为打开新行。行的展开与关闭都是通过绑定的 rowKeys 数组操作来实现。
//(这段是复制的掘金老大哥的,但是他的取消表格前的+号的css样式穿透在我这里并不起作用,他把这段逻辑梳理的很清楚,所以直接拿过来用了.嘻嘻!)
handleExpand(rowkey) {
if (this.curExpandedRowKeys.length > 0) {
let index = this.curExpandedRowKeys.indexOf(rowkey);
if (index > -1) {
this.curExpandedRowKeys.splice(index, 1);
} else {
this.curExpandedRowKeys.splice(0, this.curExpandedRowKeys.length);
this.curExpandedRowKeys.push(rowkey);
}
} else {
this.curExpandedRowKeys.push(rowkey);
}
},
onSelectChange(selectedRowKeys) {
console.log("selectedRowKeys changed: ", selectedRowKeys);
this.selectedRowKeys = selectedRowKeys;
},
},
};
</script>
<style scoped>
</style>
这是最后完成的效果
这是未去除表格前+号的效果
这是掘金老大哥的原博!!!这里解释的更加全面,我只是把我理解的总结了一下,需要的可以去欣赏文笔更精彩的总结
