Table Save/Discard Disabled binding breaks when edited #42582

Description

In the Table widget (single-row update mode), the Save/Discard column’s Disabled fields show a broken/incomplete binding in the property pane.

The Save and Discard buttons still behave correctly until those Disabled fields are edited. After the binding is changed or replaced, Save and Discard become enabled on every row, including rows that were not edited.

Steps to reproduce

1. Create an app and add a Table widget with non-empty data.
2. Set the table Update mode to Single row.
3. Make a column editable so the Save/Discard column is created.
4. Edit a cell in one row and confirm Save/Discard are enabled only on that row.
5. Open the Save/Discard column in the property pane and inspect Save → Disabled and Discard → Disabled.
6. Edit either Disabled field (for example, clear it and enter a new binding), then edit a table cell again.

Expected

• The Disabled fields show a valid per-row expression.
• After editing those fields, Save/Discard stay enabled only on rows with unsaved changes.

Actual

• The Disabled fields show a truncated/broken binding.
• After the fields are edited, Save and Discard are enabled on all rows.

Environment

• Appsmith Cloud
