How to use xlrd in Python to read merged cells

Merge cells

Operation method:

1. Use xlrd's own attributes: merged_cells

# Get the positions of all merged cells in the table and return them in list form (start row, end row, start column, end column )
merged = sheet.merged_cells #Result: [(1,5,0,1),(5,9,0,1)]

2. Use a loop to determine whether it is a merged unit The cell is still an ordinary cell, and the first row value in the merged cell is assigned to the merged cell

def get_cell_type(row_index, col_index):
  """既能得到合并单元格也能得到普通单元格"""
  cell_value = None
  for (rlow, rhigh, clow, chigh) in merged: # 遍历表格中所有合并单元格位置信息
    # print(rlow,rhigh,clow,chigh)
    if (row_index >= rlow and row_index < rhigh): # 行坐标判断
      if (col_index >= clow and col_index < chigh): # 列坐标判断
        # 如果满足条件,就把合并单元格第一个位置的值赋给其它合并单元格
        cell_value = sheet.cell_value(rlow, clow)
        print(&#39;合并单元格&#39;)
        break # 不符合条件跳出循环,防止覆盖
      else:
        print(&#39;普通单元格&#39;)
        cell_value = sheet.cell_value(row_index, col_index)
 
    # else: 添加改行后只那一个单元格的内容5,0 会返回2个值普通单元格/合并单元格
    #   print(&#39;普通单元格&#39;)
    #   cell_value = sheet.cell_value(row_index, col_index)
 
  return cell_value
# 直接输入单元格的坐标。来获取单元格内容
# print(get_cell_type(5, 0))
 
# 利用循环输出某列的单元格内容
for i in range(1, 9):
  print(get_cell_type(i, 2))

PS: The simplest operation of reading merged cells in an Excel file

Question:

1. When outputting content, use coordinates to get the print. If there is an else in the outermost layer, 2 values ​​will be returned (still confirming whether there will be other values ​​​​if there is no outermost else. The problem exists)

2. It works fine when used for the first time, but the list returned by sheet.merged_cells is empty when used again? ?

Solution: Add formatting_info=True to the open file, and it will display normally
