Enhanced Interactive Data Table

I've improved the data table to make the tab interaction more obvious and provide better visual feedback when switching between column groups:

Key Improvements:

1. Better Tab Styling:

   • Added visual emphasis to the active tab
   • Improved contrast between active and inactive tabs
   • Added font weight changes to highlight the selected tab

2. Visual Feedback for Active Tab Group:

   • Added a status indicator that shows which column group is currently active
   • Included a count of how many columns are in each group
   • Used color-coded badges to differentiate between groups

3. Improved Transitions:

   • Added transition effects for smoother column visibility changes
   • Used opacity transitions to make the appearance/disappearance more noticeable

4. Better User Guidance:

   • Added explanatory text on the page to instruct users to click on tabs
   • Used ARIA live region to announce tab changes for screen readers

5. Clearer Conditional Rendering:

   • Updated the conditional logic to use positive conditions (activeTab === "personal") instead of negative ones for better readability
   • Ensured consistent application of the same logic across header and body cells

Now when you click on any of the tabs (Main Data, Personal, Performance, or Administrative), the table will immediately respond by showing the corresponding column group while hiding the others. The active tab is clearly highlighted, and a status message confirms which group you're currently viewing.

I'll center the tab controls in the data table interface:

I've centered the tab controls by:

1. Restructuring the header section to use a vertical layout instead of a horizontal one
2. Placing the title "Employee Data" above the tabs
3. Adding a flex container with justify-center to center the tabs horizontally
4. Adjusting the padding to maintain proper spacing

Now the tabs will appear centered in the header section rather than right-aligned. The title remains prominent at the top, and the overall layout is more balanced with the tabs as the central focus of the control area.

This change makes the tab navigation more prominent and follows a common UI pattern where filtering controls are centered for emphasis and ease of access.
