所以我有一个看起来像这样的CSV：

1 | 01-01-2019 | 724
2 | 01-01-2019 | 233 | 436
3 | 01-01-2019 | 345
4 | 01-01-2019 | 803 | 933 | 943 | 923 | 954
5 | 01-01-2019 | 454
...

当我尝试使用以下代码生成dataFrame时。

df = pd.read_csv('data.csv', header=0, engine='c', error_bad_lines=False)

它仅将3列的行添加到df（上方的第1、3和5行）

其余的被认为是“坏线”，给我以下错误：

Skipping line 17467: expected 3 fields, saw 9

如何创建包含csv中所有数据的数据框，可能只是用null填充空单元格？还是在添加到df之前必须声明最大行长？

谢谢！

我已经为此查看了许多解决方案，但找不到适合我想做的事情的解决方案。

基本上我有2个CSV文件：

I have some VBA code in Excel that allows me to view the contents of a cell when I select it. Here's an example:

Here is the code for this:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
With Selection.Validation
.Delete
.Add Type:=xlValidateInputOnly, AlertStyle:=xlValidAlertStop, Operator _
:=xlBetween
.InputMessage = Target.Text
.IgnoreBlank = True
.InCellDropdown = True
.ShowInput = True
.ShowError = True
End With
End Sub

However, when I select a merged cell, I am getting the following error:
