python-pptx 实践 5：添加表格、表格填充颜色、写入数据

1、代码

# 加载库
import  os
import pandas as pd
from pptx import Presentation
from pptx.util import Cm, Pt
from pptx.enum.text import PP_ALIGN
from pptx.dml.color import RGBColor

# 设置路径
work_path = r\'E:\pyspace\tmp\pptx\'
os.chdir(work_path)

# 定义数
square_target = [20000, 1000, 1000000, 300]
square_achivement = [19000, 888, 888888, 289]
month_target = [20000, 1000, 100000, 120]
month_achivement = [18000, 888, 888888, 118]
df = pd.DataFrame(data={\'1 季度指标\': square_target,
                       \'1 季度完成\': square_achivement,
                       \'1 季度完成率\': None,
                       \'3 月份指标\': month_target,
                       \'3 月份完成\': month_achivement,
                       \'3 月份完成率\': None
                      },
                  index = [\'运营车辆（辆）\', \'运营网点（个）\', \'会员（个）\', \'净收入（万元）\']
                 )

# 计算指标完成率，将转换为百分数
df[\'1 季度完成率\'] = (df[\'1 季度完成\'] / df[\'1 季度指标\']).apply(lambda x: format(x, \'.1%\'))
df[\'3 月份完成率\'] = (df[\'3 月份完成\'] / df[\'3 月份指标\']).apply(lambda x: format(x, \'.1%\'))


# 实例化 ppt 文档对象
prs = Presentation()

# 插入幻灯片
title_only_slide = prs.slide_layouts[5]
slide_1 = prs.slides.add_slide(title_only_slide)
shapes = slide_1.shapes
shapes.title.text = \'目标达成情况\'

# 预设表格总体布局参数
rows = 5
columns = 9
left = Cm(1.5)   
top = Cm(4.5) 
width = Cm(1) 
height = Cm(1) 

# 添加表格
table = shapes.add_table(rows=rows,
                         cols=columns,
                         left=left,
                         top=top,
                         width=width,
                         height=height
                        )
table = table.table

# 调整行高、列宽
for i in range(rows):
    table.rows[i].height = Cm(1)
    
for i in range(columns):
    if i in (1, 5):
        continue
    table.columns[i].width = Cm(3)

# 写入表头
header = df.columns
for i, h in enumerate(header):
    if i >= 3:    # 第六列为空白
        i += 1
    a = i + 2
    cell = table.cell(0, a)  # 
    tf = cell.text_frame
    para = tf.add_paragraph()
    para.text = h
    para.font.size = Pt(13)
    para.alignment = PP_ALIGN.CENTER  # 居中

# 写入行名称
row_names = df.index
for i, r in enumerate(row_names):
    r = r.replace(\'（\', \'\n（\')    # 强制换行
    cell = table.cell(i+1, 0)
    tf = cell.text_frame
    para = tf.add_paragraph()
    para.text = r
    para.font.size = Pt(13)
    para.alignment = PP_ALIGN.CENTER  # 居中
    
# 按行写入数据
r, c = df.shape
for i in range(r):
    for j in range(c):
        a = j + 2  # 让开前两列
        if j >= 3:  # 第六列为空白
            a += 1
        cell = table.cell(i+1, a)
        tf = cell.text_frame
        para = tf.add_paragraph()
        para.text = str(df.iloc[i, j])
        para.alignment = PP_ALIGN.RIGHT  # 右对齐

for c in (1, 5):
    for r in range(rows):
        cell = table.cell(r, c)
        cell.fill.solid()
        cell.fill.fore_color.rgb = RGBColor(255, 255, 255)
        
# 保存 ppt
prs.save(\'test.pptx\')

效果：
