Python-在openpyxl的merged_cells集合中查找单元格引用

Question

我希望确定在openpyxl返回的merged_cells集合中是否找到工作表中的单元格。

merged_cells范围如下所示（VSCode调试器）：

我有单元格引用J31-在此集合中可以找到。如果在true集合中找到该单元格，我该如何编写一个返回merged_cells.ranges的函数？

Answer 1

<table>
  <col>
  <colgroup span="2"></colgroup>
  <colgroup span="2"></colgroup>
  <tr>
    <td rowspan="2"></td>
    <th colspan="2" scope="colgroup">Mars</th>
    <th colspan="2" scope="colgroup">Venus</th>
  </tr>
  <tr>
    <th scope="col">Produced</th>
    <th scope="col">Sold</th>
    <th scope="col">Produced</th>
    <th scope="col">Sold</th>
  </tr>
  <tr>
    <th scope="row">Teddy Bears</th>
    <td>50,000</td>
    <td>30,000</td>
    <td>100,000</td>
    <td>80,000</td>
  </tr>
  <tr>
    <th scope="row">Board Games</th>
    <td>10,000</td>
    <td>5,000</td>
    <td>12,000</td>
    <td>9,000</td>
  </tr>
</table>

^^ merged_range ^^类型必须为openpyxl.worksheet.cell_range

Answer 2

在D.Banakh的答案（+1）之前，尝试类似的操作（基于我为别人写的先前示例，因为您的问题所涉及的内容很少）：

for cell in ws.merged_cells.ranges:
    #print(cellRef +' ==> '+ str(cell.min_row) +'/'+ str(cell.max_row) +'/'+ str(cell.min_col) +'/'+ str(cell.max_col))
    if (int(cell.min_row) <= int(row) <= int(cell.max_row)) and (int(cell.min_col) <= int(col) <= int(cell.max_col)):
        print('Cell ' +cellRef+ ' is a merged cell')

上下文中的示例：

import re

cellBorders = fnGetCellBorders(ws, cellRef)
if ('T' in cellBorders) or  ('L' in cellBorders) or  ('R' in cellBorders) or  ('B' in cellBorders) or  ('M' in cellBorders):
    print('Cell has border *OR* is a merged cell and borders cannot be checked')

def getCellBorders(ws, cellRef):
    tmp = ws[cellRef].border
    brdrs = ''

    if tmp.top.style is not None: brdrs += 'T'
    if tmp.left.style is not None: brdrs += 'L'
    if tmp.right.style is not None: brdrs += 'R'
    if tmp.bottom.style is not None: brdrs += 'B'

    if (brdrs == '') and ('condTableTopLeftCell' in refs):
        if fnIsCellWithinMergedRange(ws, cellRef): brdrs = 'M'
    return brdrs

def fnIsCellWithinMergedRange(ws, cellRef):
    ans = False
    col = fnAlphaToNum(re.sub('[^A-Z]', '', cellRef))
    row = re.sub('[^0-9]', '', cellRef)
    for cell in ws.merged_cells.ranges:
        if (int(cell.min_row) <= int(row) <= int(cell.max_row)) and (int(cell.min_col) <= int(col) <= int(cell.max_col)):
            ans = True
    return ans

def fnAlphaToNum(ltr):
    ab = ["MT", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"]
    return ab.index(ltr)
