Share New Research 
Hello, I'm new, I just started using lean and jupyterlab in the research environment on my own computer
I'm reading from below link to use ‘History’ to request data, according the document, the jupyterlab is supposed to display dataframe in html table, but in my jupyterlab, the dataframe returned from History call is not displayed
I double checked by using ‘type()’ function for the variable that holds the return of ‘History’ call, the variable type is ‘pandas.core.frame.DataFrame’
did I miss any setup or something? How can I display dataframe returned from History as html table?
my code in notebook:
qb = QuantBook()
qb.SetTimeZone(TimeZones.Chicago)
qb.SetStartDate(2021, 4, 1)
qb.SetEndDate(2022, 3, 31)
spy = qb.AddEquity("SPY")
history = qb.History(spy.Symbol, Resolution.Daily) # type(history) = pandas.core.frame.DataFrame
thank you!

I'm sorry, this is not lean research jupyterlab issue, i missed 2nd parameter in the ‘History’ call, the length of the dataframe was 0, that's why there was no display, if dataframe has data, it will display html table as document presents, no setup needed
