Spire.Presentation 10.4.6 已发布。该版本支持在PPT表格的单元格中插入公式以及读取 Shape 的 CustomerData 数据。此外，一些在转换 PPT 到 PDF、SVG，以及打开文档时出现的问题也已成功被修复。详情请查看下文。

新功能:

• 支持读取Shape的CustomerData数据。

Presentation ppt = new Presentation();
ppt.LoadFromFile(inputFile);
List dataList = ppt.Slides[0].Shapes[1].CustomerDataList;
Console.WriteLine(dataList.Count);
for(int i = 0; i < dataList.Count; i++)
{
   string name = dataList[i].Name;
   string content = dataList[i].XML;
    File.WriteAllText(outputFile + name, content);

}

• 支持在表格单元格中插入公式

// 创建PPT文档
Presentation presentation = new Presentation();


Double[] widths = new double[] { 100, 100, 150, 100, 100 };
Double[] heights = new double[] { 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15 };

// 添加表格
ITable table = presentation.Slides[0].Shapes.AppendTable(presentation.SlideSize.Size.Width / 2 - 275, 90, widths, heights);

String[,] dataStr = new String[,]{
{"Name",    "Capital",  "Continent",    "Area", "Population"},
{"Venezuela",   "Caracas",  "South America",    "912047",   "19700000"},
{"Bolivia", "La Paz",   "South America",    "1098575",  "7300000"},
{"Brazil",  "Brasilia", "South America",    "8511196",  "150400000"},
{"Canada",  "Ottawa",   "North America",    "9976147",  "26500000"},
{"Chile",   "Santiago", "South America",    "756943",   "13200000"},
{"Colombia",    "Bagota",   "South America",    "1138907",  "33000000"},
{"Cuba",    "Havana",   "North America",    "114524",   "10600000"},
{"Ecuador", "Quito",    "South America",    "455502",   "10600000"},
{"Paraguay",    "Asuncion","South America", "406576",   "4660000"},
{"Peru",    "Lima", "South America",    "1285215",  "21600000"},
{"Jamaica", "Kingston", "North America",    "11424",    "2500000"},
{"Mexico",  "Mexico City",  "North America",    "1967180",  "88600000"}
};

// 在表格中添加数据
for (int i = 0; i < 13; i++)
    for (int j = 0; j < 5; j++)
    {
        //Fill the table with data
        table[j, i].TextFrame.Text = dataStr[i, j];

        //Set the Font
        table[j, i].TextFrame.Paragraphs[0].TextRanges[0].LatinFont = new TextFont("Arial Narrow");
    }

// 设置对齐方式
for (int i = 0; i < 5; i++)
{
    table[i, 0].TextFrame.Paragraphs[0].Alignment = TextAlignmentType.Center;
}
string latexMathCode = @"x^{2}+\sqrt{x^{2}+1}=2";
table[2, 3].TextFrame.Paragraphs.AddParagraphFromLatexMathCode(latexMathCode);
// 设置表格样式
table.StylePreset = TableStylePreset.LightStyle3Accent1;

// 保存结果文件
presentation.SaveToFile("Output.pptx", FileFormat.Pptx2010);
