研究方向

從 examples/react/editable-data 開始,使用 React DevTools profiler 重現編輯流程。追蹤不穩定的 cell.getContext() 參照,並判斷是範例行為還是表格行為導致所有列和儲存格重新渲染。完成標準是編輯一個儲存格不再重新渲染無關的儲存格,並且已在該範例上驗證 profiling 結果。

描述

Describe the bug

Every time one cell is edited in the examples/react/editable-data example, the entire table rerenders. If a user wants to render a large amount of rows, this strategy will start getting slow. At 50 rows in the example it takes 14.4 milliseconds to rerender the whole table with basic data. I've narrowed the unstable reference down to cell.getContext().

Your minimal, reproducible example

https://github.com/TanStack/table/tree/main/examples/react/editable-data

Steps to reproduce
  1. Open react dev tools profiler
  2. Start profiling
  3. Click on a cell to edit it
  4. Click off the cell
  5. Stop the profiler
  6. Check the results
Expected behavior

Only the affected cell should rerender unless my other cells have a direct dependency on it. I've even tried creating memoized components all the way down to the cell.

Additional context

If this is something the library doesn't support then I think there should be a documentation section on it describing the pitfalls of rendering a large amount of rows and/or using complex cells.
