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);
