Question

I'm new, I want to know if you can help me I do not understand how to select multiple cells with openpyxl and apply a border,if you could please give me an example.Thanks

Answer 1

Now you can iterate directly in the worksheet. I adapted the code
def set_border(ws, cell_range):
rows = list(ws[cell_range])
side = Side(border_style='thin', color="FF000000")
rows = list(rows) # we convert iterator to list for simplicity, but it's not memory efficient solution
max_y = len(rows) - 1 # index of the last row
for pos_y, cells in enumerate(rows):
max_x = len(cells) - 1 # index of the last cell
for pos_x, cell in enumerate(cells):
border = Border(
left=cell.border.left,
right=cell.border.right,
top=cell.border.top,
bottom=cell.border.bottom
)
if pos_x == 0:
border.left = side
if pos_x == max_x:
border.right = side
if pos_y == 0:
border.top = side
if pos_y == max_y:
border.bottom = side
# set new border only if it's one of the edge cells
if pos_x == 0 or pos_x == max_x or pos_y == 0 or pos_y == max_y:
cell.border = border
And just call it like that:
set_border(ws, 'A16:I17')

Answer 2

property is called border (not borders)
Try this:
def set_border(ws, cell_range):
rows = list(ws.iter_rows(cell_range))
side = Side(border_style='thin', color="FF000000")
rows = list(rows) # we convert iterator to list for simplicity, but it's not memory efficient solution
max_y = len(rows) - 1 # index of the last row
for pos_y, cells in enumerate(rows):
max_x = len(cells) - 1 # index of the last cell
for pos_x, cell in enumerate(cells):
border = Border(
left=cell.border.left,
right=cell.border.right,
top=cell.border.top,
bottom=cell.border.bottom
)
if pos_x == 0:
border.left = side
if pos_x == max_x:
border.right = side
if pos_y == 0:
border.top = side
if pos_y == max_y:
border.bottom = side
# set new border only if it's one of the edge cells
if pos_x == 0 or pos_x == max_x or pos_y == 0 or pos_y == max_y:
cell.border = border
