python使用openpyxl实现批量调整字体和样式_Python

使用openpyxl 批量调整字体和样式

修改字体样式 font(name,size,bold,italic,color)

from openpyxl.styles import font
from openpyxl import load_workbook

'''
font(name=字体名称,size=字体大小,bold=是否加粗,italic=是否斜体,color=字体颜色)
'''

workbook = load_workbook(filename="../exceldemo/testcase.xlsx")
sheet = workbook.active
cell = sheet["a1"]
font = font(name="微软雅黑",size=20,bold=true,italic=true,color="ff0000")
# 这个 color 是 rgb 的 16 进制表示
cell.font = font
workbook.save(filename="../exceldemo/testcase.xlsx")

效果展示：

获取表格中格子的字体样式

font.name 字体名称
font.size 字体大小
font.bold 是否加粗返回的是布尔值
font.italic 是否斜体返回的是布尔值
font.color 字体颜色返回颜色类型和相关参数

from openpyxl.styles import font
from openpyxl import load_workbook


workbook = load_workbook(filename="../exceldemo/testcase.xlsx")
sheet = workbook.active

cell = sheet["a1"]
font = cell.font
print(font.name, font.size, font.bold, font.italic, font.color)


'''
输出结果：
微软雅黑 20.0 true true <openpyxl.styles.colors.color object>
parameters:
rgb='00ff0000', indexed=none, auto=none, theme=none, tint=0.0, type='rgb'
'''

设置对齐样式 alignment(horizontal,vertical,text_rotation,wrap_text)

alignment(horizontal=水平对齐模式,vertical=垂直对齐模式,text_rotation=旋转角度,wrap_text=是否自动换行)

水平对齐：
horizontal代表水平方向，可以左对齐left，还有居中center和右对齐right，分散对齐distributed，跨列居中centercontinuous，两端对齐justify，填充fill，常规general
垂直对齐：
vertical代表垂直方向，可以居中center，还可以靠上top，靠下bottom，两端对齐justify，分散对齐distributed

workbook = load_workbook(filename="../exceldemo/testcase.xlsx")
sheet = workbook.active

cell = sheet["a3"]
alignment = alignment(horizontal="center",vertical="center",text_rotation=45,wrap_text=true)

cell.alignment = alignment
workbook.save(filename="../exceldemo/testcase.xlsx")

设置边框样式 side(style，color)

 side(style=边线样式，color=边线颜色)
 * style 参数的种类： 'double, 'mediumdashdotdot', 'slantdashdot', 
'dashdotdot','dotted','hair', 'mediumdashed, 'dashed', 'dashdot', 'thin', 
'mediumdashdot','medium', 'thick'
 
border(left=左边线样式，right=右边线样式，top=上边线样式，bottom=下边线样式)

from openpyxl.styles import side,border
from openpyxl import load_workbook


workbook = load_workbook(filename="../exceldemo/testcase.xlsx")
sheet = workbook.active

cell = sheet["d6"]
side1 = side(style="thin",color="ff0000")
side2 = side(style="thick",color="ffff0000")
border = border(left=side1,right=side1,top=side2,bottom=side2)
cell.border = border

workbook.save(filename="../exceldemo/testcase.xlsx")

展示效果：

设置填充样式 patternfill()、gradientfill()

语法：

patternfill(fill_type=填充样式，fgcolor=填充颜色）
gradientfill(stop=(渐变颜色 1，渐变颜色 2……))

from openpyxl.styles import patternfill,gradientfill
from openpyxl import load_workbook


workbook = load_workbook(filename="../exceldemo/testcase.xlsx")
sheet = workbook.active

cell_b9 = sheet["b9"]
pattern_fill = patternfill(fill_type="solid",fgcolor="99ccff")
cell_b9.fill = pattern_fill
cell_b10 = sheet["b10"]
gradient_fill = gradientfill(stop=("ffffff","99ccff","000000"))
cell_b10.fill = gradient_fill

workbook.save(filename="../exceldemo/testcase.xlsx")

展示效果：

设置行高和列宽

语法：

.row_dimensions[行编号].height = 行高
.column_dimensions[列编号].width = 列宽

from openpyxl import load_workbook


workbook = load_workbook(filename="../exceldemo/testcase.xlsx")
sheet = workbook.active

# 设置第 1 行的高度
sheet.row_dimensions[1].height = 50
# 设置 b 列的宽度
sheet.column_dimensions["b"].width = 20

workbook.save(filename="../exceldemo/testcase.xlsx")

也可以统一整张表的行高和列宽

from openpyxl import load_workbook


workbook = load_workbook(filename="../exceldemo/testcase.xlsx")
sheet = workbook.active

# 将整个表的行高设置为 50，列宽设置为 30；
sheet.row_dimensions.height = 50 
sheet.column_dimensions.width = 30 


workbook.save(filename="../exceldemo/testcase.xlsx")

合并单元格与取消合并单元格

合并单元格 merge_cells()

语法：

.merge_cells(待合并的格子编号)
.merge_cells(start_row=起始行号，start_column=起始列号，end_row=结束行号，end_column=结束列号)

from openpyxl import load_workbook


workbook = load_workbook(filename="./testcase.xlsx")
sheet = workbook.active

sheet.merge_cells("c1:d2")
sheet.merge_cells(start_row=7,start_column=1,end_row=8,end_column=3)


workbook.save(filename="./testcase.xlsx")

若合并的多个单元格中均有内容，只保留第一个单元格中的内容

效果如下：

取消合并单元格 unmerge_cells()

语法：

.unmerge_cells(待合并的格子编号)
.unmerge_cells(start_row=起始行号，start_column=起始列号，end_row=结束行号，end_column=结束列号)

from openpyxl import load_workbook


workbook = load_workbook(filename="./testcase.xlsx")
sheet = workbook.active

sheet.merge_cells("c1:d2")
sheet.merge_cells(start_row=7,start_column=1,end_row=8,end_column=3)


workbook.save(filename="./testcase.xlsx")

注意：取消合并单元格，不能恢复合并单元格所丢失的数据

效果如下：
