希望使用 openpyxl 将数据添加到命名的 excel 表中

Question

I am trying to add data to a named table in excel, but I don't know how to add additional rows to a named excel table as the openpyxl documentation is not helpful on what this package does. The best I have been able to do so far, which has not worked, is the following:

test = load_workbook(r'\\data4\users2\wyoung3\My Documents\Test.xlsx')
twb = test['Sheet2']
twbs = twb._tables
twbs = twbs.append(['s']) #this was my attempt to try and append an item to the bottom of the list
test.save(r'\\data4\users2\wyoung3\My Documents\Test.xlsx')

This resulted in a file that I could not open and the error message:

AttributeError: 'list' object has no attribute 'tableColumns'

Can anyone advise on how I can go about addressing this problem?

Answer 1

The question you are asking is not very clear, so I will provide a few options. The tutorial for openpyxl is actually decent, so you should try going through it.

First, usingTables :

from openpyxl import Workbook
from openpyxl.worksheet.table import Table, TableStyleInfo

wb = Workbook()
ws = wb.active

data = [
    ['Apples', 10000, 5000, 8000, 6000],
    ['Pears',   2000, 3000, 4000, 5000],
    ['Bananas', 6000, 6000, 6500, 6000],
    ['Oranges',  500,  300,  200,  700],
]

# add column headings. NB. these must be strings
ws.append(["Fruit", "2011", "2012", "2013", "2014"])
for row in data:
    ws.append(row)

tab = Table(displayName="Table1", ref="A1:E5")

# Add a default style with striped rows and banded columns
style = TableStyleInfo(name="TableStyleMedium9", showFirstColumn=False,
                       showLastColumn=False, showRowStripes=True, showColumnStripes=True)
tab.tableStyleInfo = style
ws.add_table(tab)
wb.save("table.xlsx")

Alternatively, if you know the cell location already, you can simply insert_rows() .

The default is one row or column. For example to insert a row at 7 (before the existing row 7):

ws.insert_rows(7)
