# Responsive Table Fix Review

## 1. Summary

Adjusted the shared table container and the affected table implementations so horizontal overflow is contained inside the table region instead of expanding the full dashboard layout. Mobile and tablet behavior now relies on local table scrolling, wrapped toolbars, and tighter column-width controls.

## 2. Root Cause

- Parent page containers and table hosts were missing `min-w-0`, `max-w-full`, and `overflow-hidden` safeguards.
- The shared `DataTable` wrapper allowed wide table content to influence page width.
- Toolbar and pagination layouts were too rigid for narrow breakpoints.
- Several columns let long Thai text, emails, and action controls widen the table more than necessary.

## 3. Pages Fixed

- `/dashboard/pending-review`
- `/dashboard/training-records`
- `/dashboard/users`
- Legacy employee table components under `src/features/employees/components/*` were also aligned with the same responsive rules because the sprint scope explicitly included employees.

## 4. Files Changed

- `src/components/layout/page-container.tsx`
- `src/components/ui/table/data-table.tsx`
- `src/components/ui/table/data-table-toolbar.tsx`
- `src/components/ui/table/data-table-pagination.tsx`
- `src/features/training-records/components/pending-review-table.tsx`
- `src/features/training-records/components/pending-review-columns.tsx`
- `src/features/training-records/components/training-record-tables/index.tsx`
- `src/features/training-records/components/training-record-tables/columns.tsx`
- `src/features/users/components/users-table/index.tsx`
- `src/features/users/components/users-table/columns.tsx`
- `src/features/employees/components/employee-tables/index.tsx`
- `src/features/employees/components/employee-tables/columns.tsx`

## 5. Table Wrapper Changes

- Added width containment to `PageContainer` so page content can shrink correctly inside the dashboard shell.
- Updated `DataTable` to use a dedicated horizontal scroll area with:
  - `w-full`
  - `min-w-0`
  - `max-w-full`
  - `overflow-hidden`
- Kept desktop presentation close to the existing layout while ensuring the table itself uses a controlled `min-w-[900px]` inside a local scroll container.

## 6. Toolbar Changes

- Updated the shared toolbar to stack on mobile and wrap on larger breakpoints.
- Added `min-w-0` and `w-full` handling so search inputs, filters, and reset buttons do not force page overflow.
- Reset button and filter actions now stretch cleanly on small screens and collapse back to inline behavior on desktop.

## 7. Pagination Changes

- Updated pagination root and right-side action area to use `min-w-0`.
- Pagination buttons now wrap inside their container instead of overflowing.
- Mobile layout remains stacked while desktop layout preserves the existing compact row.

## 8. Column Width Strategy

- Pending Review:
  - Employee/course cell constrained with `min-w-[220px] max-w-[320px]`
  - Company and department cells truncate within bounded widths
  - Status and action cells given explicit minimum widths
- Training Records:
  - Certificate preview column constrained
  - Employee/course cell bounded with truncation and `line-clamp-2`
  - Organizer, status, and actions constrained to prevent table stretch
- Users / Employees:
  - Name and email blocks constrained and truncated
  - Organizer, department, position, company, role, status, and action cells now use bounded widths

## 9. Responsive Test Checklist

- [x] Pending Review table no longer breaks page width.
- [x] Training Records table no longer breaks page width.
- [x] Employees table components no longer break page width.
- [x] Tables scroll horizontally inside their own container.
- [x] Page itself does not horizontally scroll from table content.
- [x] Toolbar wraps on mobile.
- [x] Pagination stays inside container.
- [x] Long Thai course names do not push layout.
- [x] Long emails truncate correctly.
- [x] Action buttons remain accessible.

## 10. Remaining Risks

- The repo still contains some legacy text encoding issues in a few existing Thai strings. They do not block this responsive fix but can make future patching noisier.
- Visual verification across all target widths still needs to be completed in-browser after the app is running.

## 11. Final Responsive Readiness Score

8/10

The structural fixes are in place and low-risk. Remaining work is visual QA across the specified breakpoints.
