Openpyxl 问题：删除行不移动合并的单元格

Question

我在使用 openpxyl 删除一行而不向上移动合并的单元格时遇到问题。例如，在第一张图片中，我有两个具有值 Alex 和 Bob 的合并单元格。当我删除第 2 行时，Alex 向上移动到一个单元格，Bob 被删除，合并单元格的位置保持在同一位置，而其余数据点向上移动。当正常使用 Python 之外的 excel 时，合并的单元格只会与其余数据一起向上移动。看起来 openpxyl 想要向上移动数据值但保持合并单元格的位置不变。解决这个问题的方法是什么？提前致谢！！

删除第 2 行之前：

ws.delete_rows(2)

当我删除第 2 行时，会发生以下情况：

如果您在 excel 中手动删除第二行，它应该是什么样子：

Answer 1

我找到了一个临时但不令人满意的修复方法。

如果我使用下面的代码：

for merged_cell in ws.merged_cell.ranges:
    merged_cell.shift(0,-1)
ws.delete_rows(2)

这将解决我的问题并将合并的单元格上移。但是，我对这段代码的一个问题是它向上移动了文件中所有合并的单元格。如果我只想将合并的单元格移到 A 列中，我不确定如何减少范围列表以仅包含 a.

例如，以下代码不起作用，但突出显示了我要具体实现的目标：

ws['A'].merged_cells.ranges

Answer 2

我在删除列时遇到了类似的问题，与此类列相交的合并单元格最终没有改变。

这样效果更令人满意。

代码提供了delete_row()函数，可用于模仿Excel行为，并相应移动合并单元格：

import openpyxl
from openpyxl.utils import range_boundaries
from openpyxl.utils.cell import _get_column_letter
from openpyxl.worksheet.cell_range import CellRange


def delete_row(target_row):
   # Assuming that the workbook from the example is the first worksheet in a file called "in.xlsx"
   workbook = openpyxl.load_workbook('in.xlsx')
   ws = workbook.worksheets[0]

   affected_cells = [] # array for storing merged cells that need to be moved

   row = target_row # specify the row that we want to delete
   sheet_boundary = [4,6] # specify how far to search for merged cells in the sheet in the format of [ max_col, max_row ]

   ## Define a range of cells that are below the deleted row
   # top left corner of the range; will be A2
   tl_corner = "A"+str(row)
   # bottom right corner of the row; will be D6
   br_corner = _get_column_letter(sheet_boundary[0]) + str(sheet_boundary[1])

   target_row_range_string = tl_corner+":"+br_corner

   # express all cells in the row that is to be deleted as object CellRange from openpyxl
   target_range = CellRange(range_string=target_row_range_string)


   # loop over all merged cells in the sheet
   for merged_cell_range in ws.merged_cells.ranges:
      # if merged_cell is within target_range add current merged cell to 'affected_cells'
      if merged_cell_range.issubset(target_range):
         print("Cell '"+str(merged_cell_range)+"' is within range of '"+str(target_range)+"'")
         affected_cells.append(merged_cell_range)


   # unmerge all affected cells
   for cell in affected_cells:
         # get a tuple of coordinates, instead of Xlsx notation
         cell_range = range_boundaries(cell.coord)
         print("'"+str(cell)+"' ---> '"+str(cell_range)+"'")

         # unmerge the affected cell
         ws.unmerge_cells(start_column = cell_range[0], start_row = cell_range[1],
                          end_column = cell_range[2], end_row = cell_range[3])


   # perform row deletion as usual
   ws.delete_rows(row)

   # merged all affected cells
   for cell in affected_cells:
         # get a tuple of coordinates, instead of Xlsx notation
         cell_range = range_boundaries(cell.coord)
         # merge back the affected cell, while lifting it up by one row
         ws.merge_cells(start_column = cell_range[0], start_row = cell_range[1]-1,
                        end_column = cell_range[2], end_row = cell_range[3]-1)

   # save the edited workbook
   workbook.save('out.xlsx')


# call our custom function, specifying the row you want to delete
delete_row(2)

这会找到与 target_range 相交的所有合并单元格，范围从删除的行开始，到 sheet_boundary 定义的范围结束，并首先取消合并它们。

仅更改完全在 target_range 内的合并单元格。如果合并单元格的一部分在 target_range 内，则不会对该单元格执行任何操作。

然后删除所需的行，并合并回所有受影响的单元格，同时考虑到它们已向上移动了一行。
