使用了 max-content，这里不应该再加 width 的，这样会忽略掉问题。

{ title: 'title2', dataIndex: 'b', key: 'b', width: 100 },
{ title: 'title3', dataIndex: 'c', key: 'c', width: 200 },
{ title: 'title4', dataIndex: 'd', key: 'd', width: 100 },
];

{ a: '123', key: '1' },

如果只有 noData 会不会不够，虽然没数据列头不换行了，那还有个场景（列的数据比列头少，也会换行吧？）

我目前的解法是，取 title 的元素，在第一行里 height =0 再渲染一次，撑起宽度

colGroup

<ColGroup
colWidths={mergedColumnWidth ? [...mergedColumnWidth, combinationScrollBarSize] : []}
