XLSXWriter

Question

我正在从数据帧创建 excel。 excel 的输出有 1300 列。某些列需要是 excel 中的日期格式（数据框中已经是日期时间格式）。这些列在 header.

中有“时间”一词

3 列数据的样本：

Dyn_10     Dyn_Price_10     Dyn_Time_10
-2             0.9493       44026.90764
-5             0.9625       44034.65486
0              0.9535       44035.67569
-10            0.9535       44035.67569

我现有的代码找出其中带有时间的列号，然后遍历 TimesColsNum 列表中的列并设置格式::

TimeCols = np.core.defchararray.find(CombinedDFDict[s].columns.values.astype(str), 'Time') >= 0
TimeColsNum = [i for i, x in enumerate(TimeCols) if x]
for t in TimeColsNum:
     wss.set_column(t, 20, date_format)
wb.close()

问题是我收到一个错误。我去掉这两行代码，没有报错。

for t in TimeColsNum:
     wss.set_column(t, 20, date_format)

我不知道该怎么办。我感谢所有指导。

这是回溯：

Answer 1

XlsxWriter worksheet.set_column() 的语法是：

set_column(first_col, last_col, width, cell_format, options)

在您的示例中，您只设置了其中一列。试试这个：

wss.set_column(t, t, 20, date_format)

XLSWriter - format columns from list
