Clipboard Behaves Erratically and Inconsistently During Cell Editing and Cell Browsing

[fuhan666]

The project currently experiences the following issues regarding clipboard functionality:

1. Clipboard Isolation During Cell Editing: When editing an individual cell, its clipboard content appears to be confined within that specific cell. and cannot copy content from one cell and then paste it into a different cell.
2. Separate Clipboards for Editing vs. Browsing Modes: The clipboard used when browsing data (e.g., viewing table data without entering a specific cell's edit mode) is independent of the clipboard used when editing cells. This means content copied in one mode cannot be used in the other.

Current Behavior

• In-Cell Clipboard:
  • Edit and copy text within Cell A1.
  • Pasting into Cell A1 is successful.
  • Pasting the text copied from Cell A1 into Cell B1 is not possible.
• Inter-Mode Clipboard:
  • Copy the content of Cell A1 while in data browsing mode.
  • Enter edit mode for Cell B1 and attempt to paste; the content from Cell A1 cannot be pasted.
  • Conversely, copy content while in edit mode for Cell B1.
  • Exit edit mode back to browsing mode; the previously copied content cannot be available for other operations.

Expected Behavior

• Shared Clipboard Across Cells and Modes
