+# list-table-v2 Hidden Mini Table for Row Height
+
+## Goal
+Replace the current probe row approach with a hidden mini table that uses flex boxes (not el-table-v2) to measure row height without causing visual flickering during resize/scroll.
+
+## Requirements
+1. Render a hidden container with 3-5 sample rows using pure flex boxes
+2. Width must respond to viewport changes (use container queries or width percentage)
+3. Row height from mini table used as `estimatedRowHeight` for el-table-v2
+4. No window resize event listeners - use container-based sizing
+5. No visual flickering during resize or scroll
+
+## Approach
+Instead of using a single hidden probe row that gets measured repeatedly on resize:
+- Create a mini hidden div that mimics the table's cell layout
+- The mini table's width is tied to its container (no explicit resize listener needed)
+- CSS-based layout that automatically reflows with container width
+- Use ResizeObserver ONLY on the mini table container (not window)
+
+## Technical Notes
+- Use `display: flex; flex-direction: column;` for row structure
+- Each "row" is a flex container with same padding/styling as actual table cells
+- Use `container-type: inline-size` CSS for container queries (or simple width: 100%)
+- ResizeObserver on the mini table wrapper to detect width changes
+- Only re-measure when width actually changes (debounced)
+
+## Acceptance Criteria
+- [ ] No flickering when resizing window
+- [ ] No flickering when scrolling
+- [ ] Row height updates correctly when container width changes (column flex distribution changes)
+- [ ] Hidden mini table doesn't affect layout or cause scrollbar issues
+- [ ] Build passes without errors
