Implementation Reference
- word_document_server/main.py:254-258 (handler)MCP tool handler for 'merge_table_cells'. Registered via @mcp.tool() decorator. Defines input schema via type hints and docstring. Executes by delegating to the helper function in format_tools.py.@mcp.tool() def merge_table_cells(filename: str, table_index: int, start_row: int, start_col: int, end_row: int, end_col: int): """Merge cells in a rectangular area of a table.""" return format_tools.merge_table_cells(filename, table_index, start_row, start_col, end_row, end_col)
- Core implementation of the merge_table_cells tool. Loads the Word document using python-docx, validates inputs, performs the cell merge operation using the merge_cells helper, saves the document, and returns a status message.async def merge_table_cells(filename: str, table_index: int, start_row: int, start_col: int, end_row: int, end_col: int) -> str: """Merge cells in a rectangular area of a table.
