Describe the bug and the steps to reproduce it

Rows and Cells don't have a stable keys if the row is move to another index. This cause users to lose focus if the row order change.

1. Render a table with some data with a cell that has a input field
2. Focus on the input
3. Reorder the table (programmatically)

Why this Matters

Preserves the input DOM node, keeping focus when rows get reordered.
