Hello all,
I cannot seem to get the column headers to align properly with my table.
The column headers have to be in a separate frame than the table, because I will be adding a scrollbar on the table. Below is a screenshot of the output and the code.
Any help would be appreciated.
Thanks in advance.

    # Create and populate values array

           j = 0
           values[i].append(StringVar())
           cb = ttk.Combobox(frame,width=col_widths[j],textvariable=values[i][j])
           cb.grid(row=i,  column= j)

           j += 1
           values[i].append(StringVar())
           ent = Entry(frame,width=col_widths[j],textvariable=values[i][j])
           ent.grid(row=i,  column= j)

Maybe this will get you started in the right direction.

    frame1.grid_columnconfigure(i, weight=3, uniform='columns')



for i in range(1, 4):
    header = tk.Label(frame1, text=f'Header {i}')
    header['relief'] = 'solid'
    header['borderwidth'] = 1
    header['highlightthickness'] = 1
    header['highlightbackground'] = 'grey65'
    header.grid(column=i, row=0, sticky='ew')

frame2 = tk.Frame(mainframe)
frame2.grid(column=0, row=1, sticky='new')
for i in range(1, 4):
    frame2.columnconfigure(i, weight=3, uniform='table')

table_data = ['This is some data for row 1', 'Data for row 2', 'Data for row 3. This could be anything']

column = 1
for tdata in table_data:
    data = tk.Label(frame2, text=tdata)
    data['relief'] = 'solid'
    data['borderwidth'] = 1
    data['highlightthickness'] = 1
    data['highlightbackground'] = 'grey65'
    data.grid(column=column, row=0, sticky='ew')
    column += 1

Thanks for the response.
Setting the columns as uniform for both frames seems to fix the header alignment problem.
However, when I added a scrollbar to the second frame, the header alignment problem came back.
Also, the last column disappeared.
This probably has something to do with the canvas.
Any ideas on how to fix this would be appreciated.
Below is the code.
Thanks in advance.

I've worked on this awhile and can't seem to get it align right and the scrollbar to work at the same time. Widths are right if you uncomment the scrollframe grid. But the scrollbar doesn't work. Maybe you can find a work around.
