Manage structured data

[ffffffelix]

Context

The DataTable should manage structured data and display data as a tree

Questions

• I am wondering if it will be better to directly manage the structured cell in the TableCell component and get rid of renderExpandableContent. In that way, all expandable attributes and classes will be in the root cell element.

Tasks

• We currently use two ways to know if the table is structured or not: isExpandable and row?.getCanExpand?.(). Define a single method to determine whether the data is structured.
• The action to handle opening and closing a node must be at the root cell level instead of a nested div
• Add the right aria attribute for structured view (W3C recommendation). You can also take a look at our TreeView component
