display.max_colwidth 50 The maximum width in characters of a column in the repr of a pandas data structure. When the column overflows, a “…” placeholder is embedded in the output. ‘None’ value means unlimited. display.max_info_columns 100 max_info_columns is used in DataFrame.info ...
在 openpyxl 中,可以使用 get_column_letter 方法获取列字母,然后使用 ColumnWidth 属性设置列宽度。以下是一个示例代码: # 打开 Excel 文件并设置自适应列宽 wb = Workbook() ws = wb.active for i, col in enumerate(df.columns): column_len = max(df[col].astype(str).map(len).max(), len(col)...
widths = np.max([column_widths, max_widths], axis=0) writer = pandas.ExcelWriter(excel_file_, engine='openpyxl') df.to_excel(writer, sheet_name='Sheet1', index=False) worksheet = writer.sheets['Sheet1'] for i, width in enumerate(widths, 1): ...
worksheet.column_dimensions["E"].width = 8 1. 2. 3. 4. 5. 最后保存即可: writer.save() 1. 整体完整代码: from openpyxl.styles import Alignment, Font, PatternFill, Border, Side, PatternFill import itertools writer = pd.ExcelWriter("demo3.xlsx", ...
