vue3 + antd Table组件排序filters、筛选sorter、自定义表头展示
antd Table组件使用筛选、排序、自定义设置表头显示
·
1、需求:可以自定义设置表格表头展示哪些内容,如默认展示(图一),点击表格最后一列表格的图标弹出表头的全部字段(图二),经过设置之后(图三)
图一:
图二:
图三:
2、具体实现(因为还没确认表头默认展示和全部展示的数据是否是后台返回,所以自己写了静态数据)
父组件:
html
<a-table
:columns="state.columns"
:row-key="(record) => record.id"
:data-source="state.dataSource"
:pagination="pagination"
:loading="loading"
@change="handleTableChange"

sorter: (a, b) => {
return moment(a.pt).valueOf() - moment(b.pt).valueOf()
},
},

// 初始化

let newArr = getJsonArrEqual(toRaw(props.columns), state.columnsAll); // 获取相同项
state.columnsAll.forEach(i => { // 初始化checked属性
i.checked = false;
})

</script>
<style lang="less" scoped>
.table-head-content {
.check-ul {
display: flex;
flex-wrap: wrap;
.check-li {
padding: 2px 8px;
border-radius: 4px;
margin-right: .1rem;
margin-bottom: .1rem;
white-space: nowrap;
::v-deep(.ant-checkbox-wrapper) {
width: 200px;
}
&:hover {
background: @table-head-set-bg;
}
}
.isChecked {
background: @table-head-set-bg;
}
}
};
</style>
3、json数组获取相同项方法:
// 获取两个JSON数组的相同项
export const getJsonArrEqual = (arr1, arr2) => {
var newArr = [], kvIndex = {};
for (var i = 0; i < arr1.length; i++) {
for (var j = 0; j < arr2.length; j++) {
if (arr1[i].dataIndex == arr2[j].dataIndex) {
var item
if (kvIndex[arr1[i].dataIndex] == undefined) {
kvIndex[arr1[i].dataIndex] = newArr.length;
item = {};
for (var attr in arr1[i]) item[attr] = arr1[i][attr];
newArr[kvIndex[arr1[i].dataIndex]] = item;
} else {
item = newArr[kvIndex[arr1[i].dataIndex]];
for (var attr in arr2[j]) item[attr] = arr2[j][attr];
}
}
}
}
return newArr
}
4、后面遇到一个问题,就是 columns中不一定每个项都有dataIndex(会导致数据重叠),所以改为使用title去做唯一性
export const getJsonArrEqual = (arr1, arr2) => {
var newArr = [], kvIndex = {};
for (var i = 0; i < arr1.length; i++) {
for (var j = 0; j < arr2.length; j++) {
if (arr1[i].title == arr2[j].title) {
var item
if (kvIndex[arr1[i].title] == undefined) {
kvIndex[arr1[i].title] = newArr.length;
item = {};
for (var attr in arr1[i]) item[attr] = arr1[i][attr];
newArr[kvIndex[arr1[i].title]] = item;
} else {
item = newArr[kvIndex[arr1[i].title]];
for (var attr in arr2[j]) item[attr] = arr2[j][attr];
}
}
}
}
return newArr
}
5、注意:在子组件使用到dataIndex去判断的地方也要全部改为title喔
