Element UI 之table表格表头过长使用点点…显示，并添加鼠标移入悬浮显示
需求
鼠标移入表头
关键点:
1.样式中添加:(如果在scope中会不起作用)
.el-table .cell {
word-break: keep-all !important;
white-space: nowrap !important;
}
2.在需要悬浮显示的表头文字过长处添加
:show-overflow-tooltip="true" // 表格中文字过长
:render-header="renderHeader" //表头中文字过长
3.methods中添加：
renderHeader(h, data) {
return h("span", [
h(
"el-tooltip",
{
attrs: {
class: "item",
effect: "dark",
content: data.column.label,
placement: "top",
},
},
[h("span", data.column.label)]
),
]);
},
实现
<template>
<div class="table-content">
<el-table
:data="tableData"
height="440"
:border="false"
:cell-style="cellStyle"
:header-cell-style="{
background: '#1C2E45',
height: '40px',
padding: '0',
color: '#a0b2d3',
}"
>
<template v-for="(item, index) in tableColumn">
<template v-if="item.prop == 'rank'">
<el-table-column
:key="index"
:label="item.title"
align="center"
header-align="center"
:show-overflow-tooltip="true"
:render-header="renderHeader"
>
<template slot-scope="scope">
<span
:class="[
scope.row.rank == 1 ? 'colorRank1' : 'rankColor',
scope.row.rank == 2 ? 'colorRank2' : 'rankColor',
scope.row.rank == 3 ? 'colorRank3' : 'rankColor',
]"
>{{ scope.row.rank }}</span
>
</template>
</el-table-column>
</template>
<template v-else-if="item.prop == 'monthOnMonth'">
<el-table-column
:key="index"
:label="item.title"
align="left"
header-align="center"
:show-overflow-tooltip="true"
:render-header="renderHeader"
>
<template slot-scope="scope">
<div>
<span
:class="
scope.row.monthOnMonth.slice(0, 1) == '-'
? 'triangleDown'
: 'triangleUp'
"
style="width: 10px; margin-right: 3px"
></span>
<span
:class="

? 'triangleColorRed'
: 'triangleColorGreen'
"
>{{

? scope.row.monthOnMonth.slice(1)
: scope.row.monthOnMonth
}}</span
>
</div>
</template>
</el-table-column>
</template>
<template v-else-if="item.prop == 'operation'">
<el-table-column
:key="index"
:label="item.title"
align="center"

:show-overflow-tooltip="true"
>
<template slot-scope="scope">
