Feature Request: Support custom sorting functions

[JLampeMW]

Description

Currently, the table component uses a fixed alphanumeric sorting function (sortingFn: "alphanumeric"). This limits the flexibility when working with special data types like BigInt or custom sorting requirements.

Current Limitations

• No way to specify custom sorting functions through the SortingShape interface
• Fixed alphanumeric sorting which doesn't work well for special data types
• Can't implement domain-specific sorting logic

Proposed Solution

Add support for custom sorting functions by:

1. Adding an optional sortingFn property to SortingShape interface
2. Allowing pass-through of custom sorting functions to the underlying table component
