Bugfix/index column header scroll reset

[j-gojariya]

This pull request improves the usability of the TanStack table by preserving the horizontal scroll position when sorting, especially for server-side sorting scenarios. It also adds a new Storybook story to demonstrate and test this feature. The most important changes are grouped below:

Scroll Position Preservation on Sorting:

• Added logic in useDataTable (Table.tsx) to save the scroll position before sorting and restore it after new data arrives, ensuring a smoother user experience during both client-side and server-side sorting. [1] [2]
• Updated the DraggableColumnHeader and related components to trigger scroll position saving before a sort action is initiated. [1] [2] [3]

Storybook Demonstration and Testing:

• Added a new Storybook story (ServerSideSortingTest) that simulates server-side sorting and visually demonstrates scroll position preservation, including a loading indicator and test instructions.
• Updated Storybook imports to support the new story and sorting state management.

Minor UI/Style Update:

• Added a bg-white class to table header cells for improved appearance.

Other:

• Bumped the package version in package.json to 1.0.60.
