Python “如何修复”；ValueError:长度不匹配“；

我得到一个错误：

ValueError: Length mismatch: Expected axis has 5 elements, new values have 6 
elements

当我运行基本代码时：

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd 

READ = "C:\\Users\\Ashley\\Biotech Data Center 4.1.21.xlsx"

stocks = "BHVN"

PipelineData = pd.read_excel(READ, sheet_name='Sheet1', header=None, index_col=0)
pipelinecolstitle = pd.read_excel(READ, sheet_name='Sheet1', header=None,nrows=1).values[0]
PipelineData.columns = pipelinecolstitle
colspipe= ['Catalyst']
tt = PipelineData[colspipe]

for i in stocks:
    t = tt.loc[(PipelineData['Ticker']==i)]
    print(t)
    
    fig, ax = plt.subplots()
    cols = ["Catalyst"]

    axMain = plt.subplot(2,1,1)
    table = plt.subplot(2,1,2, frameon=False)

    axMain.plot([1,2,7])
    table = ax.table(cellText=t, loc='upper center',colLabels=cols)
    table.axis("off")

plt.show()

它似乎不喜欢index_col=0

---

如果我更改索引\u col=None，它会给我一个键错误：0

此错误可能是由此赋值引起的

PipelineData.columns=pipelinecolstitle

，这意味着PipelineData的列数不等于pipelinecolstitle长度

---

检查是否

PipelineData.shape[1]==len（pipelinecolstitle）

请提供重现错误的示例数据。它们在6处相等。
