Edit Table in PowerPoint document

Spire.Presentation is a powerful and easy-to-use .NET component, especially designed for developers. Using Spire.Presentation you can generate, modify, convert, render, and print documents without installing Microsoft PowerPoint on your machine. There is a document in our website introducing you how to insert table. And in this document, you will be introduced how to edit a table within a PPT document.

Step 1: Create a Presentation instance and load the file.

Presentation presentation = new Presentation();
presentation.LoadFromFile("table.pptx");

Step 2: Store the data used in replacement in string [].

string[] str = new string[] { "Germany", "Berlin", "Europe", "0152458", "20860000" };

Step 3: Get the table within the PPT document.

ITable table = null;
foreach (IShape shape in presentation.Slides[0].Shapes)
{
    if (shape is ITable)
    {
        table = (ITable) shape;
    }
}

Step 4: Fill in the third row with new data and set the HighlightColor.

for (int i = 0; i < table.ColumnsList.Count;i++ )
{
    //replace the data in cell
    table[i, 2].TextFrame.Text = str[i];

    //set the highlightcolor
    table[i, 2].TextFrame.TextRange.HighlightColor.Color = Color.BlueViolet;
}

Step 5: Set the style of the table.

table.StylePreset = TableStylePreset.LightStyle1Accent2;

Step 6: Save the document.

presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
