我有一个excel文件,我将其用作模板,我可以根据需要添加信息。
我有特殊的样式和合并需要在几个单元格范围内完成,但是当我有大量数据时,我现在正在这样做的方式(强制它)非常慢。
有没有办法让我做得更好?
for a in xrange(1, len(plans)):
offset = 3 * a
# Create blank templates for plans
for x in xrange(5, 549):
first_col_cell = recommended.cell(row=x, column=4)
second_col_cell = recommended.cell(row=x, column=5)
third_col_cell = recommended.cell(row=x, column=6)
new_first_col_cell = recommended.cell(row=x, column=4 + offset)
new_second_col_cell = recommended.cell(row=x, column=5 + offset)
new_third_col_cell = recommended.cell(row=x, column=6 + offset)
if third_col_cell.has_style and x != 42:
new_third_col_cell.font = copy(third_col_cell.font)
new_third_col_cell.border = copy(third_col_cell.border)
new_third_col_cell.fill = copy(third_col_cell.fill)
new_third_col_cell.number_format = copy(third_col_cell.number_format)
new_third_col_cell.protection = copy(third_col_cell.protection)
new_third_col_cell.alignment = copy(third_col_cell.alignment)
new_third_col_cell.value = copy(third_col_cell.value)
if second_col_cell.has_style and x != 42:
new_second_col_cell.font = copy(second_col_cell.font)
new_second_col_cell.border = copy(second_col_cell.border)
new_second_col_cell.fill = copy(second_col_cell.fill)
new_second_col_cell.number_format = copy(second_col_cell.number_format)
new_second_col_cell.protection = copy(second_col_cell.protection)
new_second_col_cell.alignment = copy(second_col_cell.alignment)
new_second_col_cell.value = copy(second_col_cell.value)
if first_col_cell.has_style and x != 42:
new_first_col_cell.font = copy(first_col_cell.font)
new_first_col_cell.border = copy(first_col_cell.border)
new_first_col_cell.fill = copy(first_col_cell.fill)
new_first_col_cell.number_format = copy(first_col_cell.number_format)
new_first_col_cell.protection = copy(first_col_cell.protection)
new_first_col_cell.alignment = copy(first_col_cell.alignment)
new_first_col_cell.value = copy(first_col_cell.value)
if (x >= 6 and x <= 33) or x == 36 or x == 41 or x == 44:
recommended.merge_cells(start_row=x, start_column=4 + offset, end_row=x, end_column=6 + offset)
if first_col_cell.has_style:
recommended_merge = colnum_string(4 + offset) + str(x) + ':' + colnum_string(6 + offset) + str(x)
style_border(recommended, recommended_merge, border)
second_col_cell.border = copy(first_col_cell.border)
third_col_cell.border = copy(first_col_cell.border)
这也是calnum_string函数,如果需要的话:
def colnum_string(n):
div=n
string=""
while div>0:
module=(div-1)%26
string=chr(65+module)+string
div=int((div-module)/26)
return string
答案 0 :(得分:2)
工作量是要复制六种样式,例如
new_third_col_cell.font = copy(third_col_cell.font)
尝试仅复制样式引用,而不是分配新样式,例如
target_cell._style = copy(source_cell._style)
每个样式可以节省~10%,如果并非所有样式都可以在所有单元格中使用。
仅复制使用的样式,例如:
if source_cell._style.fontId: target_cell.font = copy(s_cell.font)
...
除此之外,请考虑 slim 您的代码,例如:
def copy_style(s_cell, t_cell):
...
def merge_cells(ws, row, offset, columns_456):
...
def main(recommended, plans):
column_456 = [4,5,6]
for a in xrange(1, len(plans)):
offset = 3 * a
# Create blank templates for plans
for x in xrange(5, 549):
if x != 42:
for column in column_456:
cell = recommended.cell(row=x, column=column)
if cell.has_style:
copy_style(cell, recommended.cell(row=x, column=column+offset))
if (x >= 6 and x <= 33) or x == 36 or x == 41 or x == 44:
merge_cells(recommended, x, offset, column_456)
