React 单选行 radio
配置 type: 'radio' 列实现行单选(互斥),通过 onRadioChange 监听、ref 上的 getSelectedRadio() / setSelectedRadio() 读写选中行。
使用的 API
ts
type Column = {
key: string; // 列标识(必填)
title: string; // 列标题(必填)
width: number; // 列宽(必填)
type: 'radio'; // 特殊列类型:单选列
fixed?: 'left' | 'right'; // 冻结列
}
type Options = {
list: T[]; // 数据列表
itemKey: string; // 行唯一标识字段名
estimatedSize: number; // 行预估高度(px)
onRadioChange?: (row: T) => void; // 选中行变化回调
}
// 实例方法(ref 上调用)
tableRef.current?.getSelectedRadio();
tableRef.current?.setSelectedRadio(rowKey); // 传 null 清除示例
