如果新加的 type 不需要 xSearchItems ，可以这样合并：
```typescript type Column = { xSearchType: 'input' | 'other' | 'other-other' } | { xSearchType: 'select', xSearchItems: any[] } ``` |

应该可以用 conditional type

```typescript
type column<T> = T extends 'select' ? { xSearchType: T, xSearchItems: any[] } : { xSearchType: T } let c: column<'select'> = { xSearchType: 'select', xSearchItems: [], } let n: column<'input'> = { xSearchType: 'input', } ``` 暂时想到这样写，不过感觉还有更简洁的方法。 |
