Answer 1

Let's say you want to add 3 rows at the top of your table, you'll first have to shift down the merged cells and then insert the rows; For this we are going to use the shift(col_shift=0, row_shift=0) method;

Help on method shift in module openpyxl.worksheet.cell_range:

shift(col_shift=0, row_shift=0) method of openpyxl.worksheet.cell_range.CellRange instance
    Shift the range according to the shift values (*col_shift*, *row_shift*).

    :type col_shift: int
    :param col_shift: number of columns to be moved by, can be negative
    :type row_shift: int
    :param row_shift: number of rows to be moved by, can be negative
    :raise: :class:`ValueError` if any row or column index < 1

The number of rows you want to insert must coincide with the numbers of rows you shift; So for your example you'll just have to:

merged_cells_range = ws.merged_cells.ranges
for merged_cell in merged_cells_range:
    merged_cell.shift(0,3)
ws.insert_rows(1,3)

So in the end the merged cells are preserved
