如果你想使用`rowClassName`属性来实现表格单元格背景色设置,并且前三列不设置,可以参考以下代码实现:
```html
<template>
<a-table :columns="columns" :data-source="data" :row-class-name="rowClassName"></a-table>
</template>
<script>
export default {
data() {
return {
columns: [
{
title: "Name",
dataIndex: "name",
key: "name",
},
{
title: "Age",
dataIndex: "age",
key: "age",
},
{
title: "Address",
dataIndex: "address",
key: "address",
},
],
data: [
{
key: 1,
name: "John Brown",
age: 32,
address: "New York No. 1 Lake Park",
},
{
key: 2,
name: "Jim Green",
age: 42,
address: "London No. 1 Lake Park",
},
{
key: 3,
name: "Joe Black",
age: 32,
address: "Sidney No. 1 Lake Park",
},
{
key: 4,
name: "Jim Red",
age: 32,
address: "London No. 2 Lake Park",
},
{
key: 5,
name: "Jake White",
age: 32,
address: "Dublin No. 2 Lake Park",
},
],
};
},
methods: {
rowClassName(record, index) {
if (index > 2) {
return "custom-row";
} else {
return "";
}
},
},
};
</script>
<style>
.custom-row td {
background-color: #f0f0f0;
}
</style>
```
在上述代码中,我们通过`rowClassName`方法来自定义表格行的类名,并在前三行不设置自定义类名。具体实现中,我们在`rowClassName`方法中判断当前行的索引是否大于2,如果是,则返回自定义类名`custom-row`,否则返回空字符串。同时,我们在样式中设置`.custom-row td`选择器的背景色为`#f0f0f0`,实现表格单元格的背景色设置。
