Custom Sorting in Taipy Tables

[FlorianJacta]

Description:

Currently, Taipy’s built-in tables support basic sorting capabilities. However, there is no direct support for custom-defined sorting strategies. This can be limiting in scenarios where complex or domain-specific sorting logic is required. For example, users may want to sort by a custom metric, sort strings numerically, apply locale-aware sorting, or handle hierarchical data structures in a custom manner.

Proposed Solution:

Introduce a property or callback mechanism on Taipy table components that allows the developer to define a custom sorting function for each column.
The sorting function could be provided with the column’s current dataset subset and the sorting parameters (e.g., ascending/descending), and return a rearranged dataset.
Provide documentation and examples demonstrating how developers can implement their own sorting logic.

Example Use Case:

A user has a table of alphanumeric codes (e.g., "A10", "A2", "A100") and wants the table to sort them numerically rather than lexicographically so that "A2" < "A10" < "A100". Another user may need to integrate a custom business rule, like sorting by another hidden field or sorting dates with a custom parser.
