如何使用openpyxl过滤列数据

Question

我正在尝试对现有 Excel 文件应用过滤器，并将其导出到另一个 Excel 文件。我想提取仅包含值 16 的行，然后将 table 导出到另一个 excel 文件（如下图所示）。

我已经尝试多次阅读 openpyxl 文档并在谷歌上搜索解决方案，但我仍然无法使我的代码正常工作。我还附上了下面的代码和文件

import openpyxl
# Is use to create a reference of the Excel to wb
 wb1 = openpyxl.load_workbook('test_data.xlsx')
 wb2 = openpyxl.load_workbook('test_data_2.xlsx')

# Refrence the workbook to the worksheets
 sh1 = wb1["data_set_1"]
 sh2 = wb2["Sheet1"]

 sh1.auto_filter.ref = "A:A"
 sh1.auto_filter.add_filter_column(0, ["16"])
 sh1.auto_filter.add_sort_condition("B2:D6")

 sh1_row_number = sh1.max_row
 sh1_col_number = sh1.max_column

 rangeSelected = []
 for i in range(1, sh1_row_number+1, 1):
     rowSelected = []
     for j in range(1, sh1_col_number+1, 1):
         rowSelected.append(sh1.cell(row = i, column = j))
     rangeSelected.append(rowSelected)

  del rowSelected

 for i in range(1, sh1_row_number+1, 1):
    for j in range(1, sh1_col_number+1, 1):
        sh2.cell(row = i, column = j).value = rangeSelected[i-1][j-1].value

 wb1.save("test_data.xlsx")
 wb2.save("test_data_2.xlsx")

自动过滤器实际上并不过滤数据，它只是为了可视化。您可能希望在循环浏览工作簿时进行过滤。请注意，我假设您在第二个工作簿中已经有了 table headers 代码。它不会覆盖数据，它附加到 table.

import openpyxl
# Is use to create a reference of the Excel to wb
wb1 = openpyxl.load_workbook('test_data.xlsx')
wb2 = openpyxl.load_workbook('test_data_2.xlsx')

# Refrence the workbook to the worksheets
sh1 = wb1["data_set_1"]
sh2 = wb2["data_set_1"]   # use same sheet name, different workbook

for row in sh1.iter_rows():
    if row[0].value == 16:   # filter on first column with value 16
        sh2.append((cell.value for cell in row))     

wb1.save("test_data.xlsx")
wb2.save("test_data_2.xlsx")
