Writing tables to different sheets in an Excel file

import pandas as pd
import Reporter as rp

view = rp.ReportSubject()

view.attach(rp.ExcelObserver())


data = pd.DataFrame({"col1": [1, 2], "col2": [3, 4]})
data2 = pd.DataFrame({"a": ["cell 1", "cell 2"], "b": ["cell 3", "cell 4"]})
data3 = pd.DataFrame({"catalan": [1, 1, 2, 5, 14, 42, 132]})


# output the number of tables indicated by the sheet name
view.notify(rp.ExcelExportEvent({"Sheet With 1 Table": [rp.ExcelDf(data)],
                                 "Sheet With 2 Tables": [rp.ExcelDf(data), rp.ExcelDf(data2, startcol = 3)],
                                 "Sheet With 3 Tables": [rp.ExcelDf(data), rp.ExcelDf(data2, startcol = 3), rp.ExcelDf(data3, startcol = 6)]} ,"output.xlsx"))

Output Result

Reading only a portion of a table not centered at A1
