Is it possible to throw custom component into the column header (SheetComponent)?

[corocoto]

Hello,

I am currently working with the SheetComponent from the @antv/s2-react library and have encountered a limitation regarding the customization of the header content in the table.

I have referred to the documentation on the official website, specifically the section on customization (https://s2.antv.antgroup.com/en/api/general/s2-data-config#fields), which mentions the use of the CustomTreeNode interface for this purpose. However, I have found that the parameters provided are insufficient for my needs.

The current customization options do not seem to allow for the injection of a custom component directly into the header cell, which would enable a complete overhaul of the header content. This limitation restricts the ability to fully customize the appearance and functionality of the header cells in the SheetComponent.

Could you please provide guidance on how to achieve this level of customization? If this feature is not currently supported, I would like to request the addition of a parameter or method that allows for the integration of custom components within header cells.

P.S. But I can understand that it can be full limitation, because render process is happening on the canvas side. And throwing custom components via props and their full rendering with saved custom logic functionality sounds crazy.

It seems that you are looking to inject custom components into the column header of the SheetComponent in the @antv/s2-react library, and the current customization options do not meet your needs. As of now, if the library does not support this feature directly, it might require a feature request or a workaround.

Here's what you can do:

1. Feature Request: Since you mentioned that the current options are insufficient, you can request this feature to be added to the library. This would involve adding a parameter or method to allow custom components in header cells.

2. Workaround: Depending on the flexibility of the library, you might be able to achieve this by manipulating the DOM or using additional libraries to render custom components in the header. However, this approach might be complex and not recommended unless you are familiar with the library's internals.

3. Community and Support: Engage with the community or the maintainers of the library to see if there are any undocumented features or upcoming updates that might support this functionality.

If you would like to proceed with a feature request, you can express your need for this feature on the library's GitHub page or discussion forums. This will help the maintainers understand the demand and possibly prioritize it in future updates.

If you have any further questions or need assistance with a specific workaround, feel free to ask!

@corocoto Hey there! 👋 I'm not entirely sure what your exact needs are here. If you're trying to customize column header cells, you might want to check out this col-cell customization example. You can achieve custom styling by extending/overriding the col-cell class at packages/s2-core/src/cell/col-cell.ts.

👋 If you're asking about rendering React components inside column header cells, I'd generally advise against mixing DOM elements with Canvas rendering unless absolutely necessary. This approach might lead to unexpected issues like:

⚠️ Z-index conflicts (Canvas vs DOM layers)
⚠️ Performance bottlenecks with frequent re-renders
⚠️ Coordinate synchronization headaches

But if you must render DOM elements in headers, check out AntV's HTML Custom Node docs.

If this isn't what you're looking for, could you:

1. Share a screenshot/mockup of your desired effect? 🖼️
2. Clarify which specific aspects you want to customize? (e.g., styling, interactions, rendering content)

That'll help me give more targeted suggestions! 🔍

Thanks a lot! The second part of answer is what I need. I'll learn about pros & cons, and do a research about this solution to make the right decision

Yeah, you're absolutely right. Thanks for providing information about possible leading issues!
