PowerPoint 中的表格是一种以结构化格式组织和呈现数据的方法，类似于 Excel 或 Word 等其他应用程序中表格的使用方式。它们提供了一种清晰简洁的方式来显示信息，使您的受众更容易消化和理解内容。

用于在 PowerPoint 演示文稿中创建或提取表格的 Python 库

要使用 Python 在 PowerPoint 演示文稿中创建或提取表格，我们可以使用 Spire.Presentation for Python 库。

Spire.Presentation for Python 是一个功能丰富且用户友好的库，支持在 Python 应用程序中创建、读取、编辑和转换 PowerPoint 演示文稿。使用此库，您可以对 PowerPoint 演示文稿执行各种操作，包括添加文本或图像、插入形状、创建表格和图表、添加或删除幻灯片、隐藏或显示幻灯片、合并或拆分演示文稿、加密或解密演示文稿、添加水印、插入视频和音频、添加评论等等。此外，您还可以将 PowerPoint 演示文稿转换为各种文件格式，例如 PDF、图像、HTML、SVG、ODP、OFD 和 XPS。

您可以使用以下 pip 命令从 PyPI 安装适用于 Python 的 Spire.Presentation：

pip install Spire.Presentation

有关安装的更多详细信息，您可以查看此官方文档：如何在 VS Code 中为 Python 安装 Spire.Presentation。

使用 Python 在 PowerPoint 演示文稿中创建表格

可以使用 ISlide.Shapes.AppendTable（） 函数将表格添加到 PowerPoint 幻灯片中。添加表后，您可以使用 ITable[columnIndex， rowIndex] 用数据填充单元格。TextFrame.Text 属性。

下面是一个简单的示例，演示如何在 Python 中向 PowerPoint 幻灯片添加表格：

from spire.presentation.common import *
from spire.presentation import *
import math

# Create a new PowerPoint presentation
presentation = Presentation()
# If you want to load an existing presentation, add this line
# presentation.LoadFromFile("input_file_path")

# Get the first slide in the presentation
slide = presentation.Slides[0]

# Define the widths of columns in the table
column_widths = [110, 100, 150, 100]
# Define the heights of rows in the table
row_heights = [15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15]

# Calculate the total width of the table
total_width = sum(column_widths)

# Specify the x and y coordinates to add the table
x = math.trunc(presentation.SlideSize.Size.Width / float(2)) - (total_width / 2)
y = 100

# Add a table to the slide
table = slide.Shapes.AppendTable(x, y, column_widths, row_heights)

# Define the data for the table
table_data = [
    ["Employee", "Department", "Job Title", "Salary"],
    ["John Doe", "Sales", "Sales Manager", "$85,000"],
    ["Jane Smith", "Marketing", "Marketing Coordinator", "$52,000"],
    ["Bob Johnson", "IT", "Software Engineer", "$95,000"],
    ["Emily Davis", "HR", "HR Specialist", "$62,000"],
    ["Michael Wilson", "Finance", "Financial Analyst", "$78,000"],
    ["Sarah Lee", "Operations", "Operations Manager", "$90,000"],
    ["David Kim", "R&D", "Research Scientist", "$85,000"],
    ["Olivia Chen", "Marketing", "Marketing Specialist", "$58,000"],
    ["Tom Nguyen", "IT", "IT Support Technician", "$48,000"],
    ["Samantha Brown", "HR", "Recruitment Coordinator", "$55,000"]
]

# Populate the table with the data
for i, row in enumerate(table_data):
    for j, cell_value in enumerate(row):
        table[j, i].TextFrame.Text = cell_value
        # Set the font and font size for the text in each cell
        table[j,i].TextFrame.Paragraphs[0].TextRanges[0].LatinFont = TextFont("Arial")
        table[j,i].TextFrame.Paragraphs[0].TextRanges[0].FontHeight = 12
        # Center the text in each cell
        table[j, i].TextFrame.Paragraphs[0].Alignment = TextAlignmentType.Center
        
# Apply a built-in table style to the table
table.StylePreset = TableStylePreset.LightStyle3Accent5

# Save the PowerPoint presentation to a file
presentation.SaveToFile("CreateTable.pptx", FileFormat.Pptx2010)
presentation.Dispose()

使用 Python 在 PowerPoint 幻灯片中插入表格

使用 Python 从 PowerPoint 演示文稿中提取表格

PowerPoint 幻灯片中的表格由 ITable 对象表示。因此，要提取表，您首先需要找到 ITable 类型的形状，然后遍历表中的单元格并使用 Cell.TextFrame.Text 属性获取单元格的数据。

下面是一个简单的示例，演示如何使用 Python 从 PowerPoint 演示文稿中提取表：

from spire.presentation.common import *
from spire.presentation import *

# Initialize an instance of the Presentation class
presentation = Presentation()

# Load a PowerPoint presentation containing tables
presentation.LoadFromFile("CreateTable.pptx")

# Create a list to store the extracted table data
table_data = []

# Traverse through the slides in the presentation
for slide in presentation.Slides:
    # Traverse through the shapes on each slide
    for shape in slide.Shapes:
        # Check if the current shape is a table
        if isinstance(shape, ITable):
            table = shape
            
            # Get the data of the cells in the table and append them to the list
            table_data.extend([" | ".join(cell.TextFrame.Text.strip() for cell in row) for row in table.TableRows])
            table_data.append("")

# Write the table data to a text file
with open("table.txt", "w", encoding="utf-8") as file:
    file.write("\n".join(table_data))

presentation.Dispose()
