用python如何绘制表格不同颜色的excel

需求：

需求简单：但是感觉最后那部分遍历有意思：s型数组赋值，考虑到下标，简单题

先实现个差不多的

m = 5
cols = 9
rows = 4
nums = [0, 1]
array = [[-1 for _ in range(9)] for _ in range(4)]
i, j = 0, 0
t = 0
index = -1
while t < cols * rows:
    if i % rows == 0 and i > 0:
        j += 1
        i -= 1
    if i < 0:
        j += 1
        i += 1
    # if t % m == 0:
    #     index = (index + 1) % len(nums)
    array[i][j] = t  # index
    if j % 2 == 0:  # 0,2,..2n 下
        i += 1
    else:  # 1,3, 2n+1 上
        i -= 1
    t += 1
 
for i in range(4):
    print(array[i])

需求代码：

from openpyxl import workbook
from openpyxl.styles import patternfill, side, border
 
# 仿照excel格式
# excel文件路径
file_path = 'c:/users/lenovo/desktop/工作簿2.xlsx'
 
colors = ['000000', '44546a', 'cc00ff', '00008b']
colorslen = len(colors)
fills = [patternfill("solid", fgcolor=color) for color in colors]
workbook = workbook()
sheet = workbook.create_sheet("sheet1", 0)
rows, cols = 19, 9
colorindex = -1
block_height = 5
 
# 按行
for i in range(int(rows / block_height)):
    for j in range(cols):
        colorindex = (colorindex + 1) % colorslen
        for p in range(block_height):
            row = block_height * i + p
            col = j 
            cell = sheet.cell(column=col + 1, row=row + 1)
            cell.fill = fills[colorindex]
            cell.border = border(left=side(style='thin'),
                                 right=side(style='thin'),
                                 top=side(style='thin'),
                                 bottom=side(style='thin'))
 
# 按列
if rows % block_height != 0:
    newrows = rows % block_height
    prerows = rows - rows % newrows - 1
    newcols = cols
    i, j = 0, 0
    t = 0
    while t < newcols * newrows:
        if i % newrows == 0 and i > 0:
            j += 1
            i -= 1
        if i < 0:
            j += 1
            i += 1
        if t % block_height == 0:
            colorindex = (colorindex + 1) % colorslen
        cell = sheet.cell(column=j + 1, row=prerows + i + 1)
        cell.fill = fills[colorindex]
        cell.border = border(left=side(style='thin'),
                             right=side(style='thin'),
                             top=side(style='thin'),
                             bottom=side(style='thin'))
        if j % 2 == 0:  # 0,2,..2n 下
            i += 1
        else:  # 1,3, 2n+1 上
            i -= 1
        t += 1
 
workbook.save(file_path)
 
# 下面是学习读取的部分代码
# wb = openpyxl.load_workbook(file_path)
# sheet_name = 'sheet1'
# sheet = wb.get_sheet_by_name(sheet_name)
# for r in range(1, sheet.max_row + 1):
#     for c in range(1, sheet.max_column + 1):
#         item = sheet.cell(row=r, column=c)
#         print(item, end=' ')
#     print()
# wb.save(file_path)

颜色没对上，意思差不多就行了
