因为懂你，所以永恒！

--python

如果你也和我一样，想通过python处理excel文件。那这篇文章基本上可以满足你的需要。代码中的文件路径可以自己修改！

from openpyxl import Workbook
from openpyxl.utils import get_column_letter
from openpyxl.styles import Alignment
from openpyxl.styles import Font
import pandas as pd
import os

# 创建新工作簿
wb = Workbook()
ws = wb.active
ws.title = "Component List"

# 设置字体
ws.font = Font(name='Arial', size=12, bold=True, color='FF0000')

# 设置列宽    （可选） 
for col in range(1, 8):     # 设置前7列
    letter = get_column_letter(col)
    ws.column_dimensions[letter].width = 30

# 定义表头
headers = ["Item", "Quantity", "Part Reference", "PCB", "电性件两套所", "考核板两套所", "现有采购"]
ws.append(headers)

# 添加数据行（示例）：直接添加第二列到第七列的数据，第一列由计数器自动生成
data_rows = [
    [10-1,  "REF001", "PCB001", "Elec001", "Test001", "Purchase001"],
    [5-2,   "REF002", "PCB002", "Elec002", "Test002", "Purchase002"],
    [5-3,   "REF003", "PCB003", "Elec003", "Test003", "Purchase003"]
]

# 初始化计数器
item_counter = 1

# 逐行添加数据并动态生成 Item 列的值
for row in data_rows:
    full_row = [item_counter] + row   # 将 Item 列和其余列拼接在一起
    ws.append(full_row)
    item_counter += 1

left_alignment = Alignment(horizontal='left', vertical='center', wrap_text=True)
for row in ws.iter_rows( min_row=1, max_row=1):
    for cell in row:
        cell. alignment = left_alignment     # 应用对齐设置

# 保存文件
wb.save("Component_list.xlsx")
print("Component list has been created and saved as 'Component_list.xlsx'.")

# 读取文件     （可选）
df = pd.read_excel("D:/PyQt_Prj/Component_list.xlsx")

# 调整 DataFrame 的显示格式，使数据对齐并去除索引列
print(df.to_string(index=False))   # 去掉默认的索引列
