+# Nimble Editable Table (IxD)
+
+## Overview
+
+Nimble table support for interactive cell editing.
+
+### Background
+
+-   [ViD spec](https://www.figma.com/file/PO9mFOu5BCl8aJvFchEeuN/Nimble_Components?type=design&node-id=5308-156796&mode=dev)
+-   [Component Issue](https://github.com/ni/nimble/issues/1876)
+
+## Usage
+
+**When to use:**
+
+Use an editable table when you need to allow users to modify individual cells directly within the table.
+This is particularly useful for scenarios where inline editing is required, such as data entry, spreadsheet-like applications, or any situation where quick and efficient data manipulation is necessary.
+
+**When not to use:**
+
+-   When data integrity is critical and the table should not be modified by users.
+-   When the table is used for displaying static or read-only data.
+-   When the table contains sensitive information that should not be editable.
+-   When the user interface requires a more complex data entry form.
+
+## Anatomy

+| --------------------- | ------------------------------------------------------------------------ |
+| Static cell value     | Non-editable display of cell value                                       |
+| Action button         | Button to open cell context menu. Appears on row hover or keyboard focus |

+
+### ARIA Considerations
+
+-   Maintain compatibility with existing keyboard navigation behavior
+-   Consider resolving [existing ARIA gaps](https://github.com/ni/nimble/issues/2285)
+
+### Mouse Interactions
+
+![Editable cell mouse navigation](./spec-images/editable-cell-mouse-navigation.png)
+
+-   Editable table cells show the same row hover state as non-editable cells on mouse hover.
+    -   I.e. When hovering over a row, the action menu button appears. Depending on the table's selection mode, the row may be highlighted.
+-   Single clicking editable cell shows the cell focus state.
+-   Double clicking the editable cell transforms the cell into an input control in the focus state.
+-   Clicking away from a focused editable cell sets the value and transforms it into the Cell focus state.
+
+### Non-Mouse Interactions
+
+![Editable cell key navigation](./spec-images/editable-cell-key-navigation.png)
+
+-   When a cell has keyboard focus (Cell focus state), pressing `TAB` or `ENTER` transforms the cell into an input control in the focus state (Edit focus state).
+-   When a cell has Edit focus, pressing `TAB` moves the focus to the action button, or to the next available focus target.
+
+![Editable cell enter key](./spec-images/editable-cell-enter-key.png)
+
+-   When a cell has Edit focus, pressing `ENTER` sets the value and transforms it into the Cell focus state.
+
+![Editable cell escape key](./spec-images/editable-cell-escape-key.png)
+
+-   When a cell has Edit focus, pressing `ESCAPE` reverts any value change and transforms it into the Cell focus state.
+
+#### Touch-Screen Devices
+
+-   The edit workflow should support touch screen devices.
