Insert a table into a PowerPoint Presentation in C# and VB.NET
You can use the ISlide.Shapes.AppendTable(float x, float y, double[] widths, double[] heights) method to add a table to a specific slide of a PowerPoint presentation. The detailed steps are as follows:
- Initialize an instance of the Presentation class.
- Load a PowerPoint presentation using Presentation.LoadFromFile(string file) method.
- Get a specific slide using Presentation.Slides[int index] property.
- Define two double arrays, widths and heights, which specify the number and size of rows and columns in table.
- Add a table with the specified number and size of rows and columns to a specific position on the slide using ISlide.Shapes.AppendTable(float x, float y, double[] widths, double[] heights) method.
- Store the table data in a two-dimensional string array.
- Loop through the string array, and assign the corresponding data to each cell of the table using ITable[int columnIndex, int rowIndex].TextFrame.Text property.
- Set the alignment of the first row of the table to center.
- Apply a built-in style to the table using ITable.StylePreset property.
- Save the presentation using Presentation.SaveToFile(string file, FileFormat fileFormat) method.
- C#
- VB.NET
using Spire.Presentation;
namespace InsertTable
{
internal class Program
{
static void Main(string[] args)
{
//Initialize an instance of the Presentation class
Presentation presentation = new Presentation();
//Load a PowerPoint presentation
presentation.LoadFromFile(@"Input.pptx");
//Get the first slide
ISlide slide = presentation.Slides[0];
//Define two double arrays, widths and heights, which specify the number and size of rows and columns in table
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 };
//Add a table with the specified number and size of rows and columns to a specific position on the slide
ITable table = slide.Shapes.AppendTable(presentation.SlideSize.Size.Width / 2 - 275, 90, widths, heights);
//Store table data in a two-dimensional string array
string[,] data = new string[,]{

//Loop through the string array and assign data to each cell of the table
for (int i = 0; i < 13; i++)
for (int j = 0; j < 5; j++)
{
//Fill each cell of the table with data
table[j, i].TextFrame.Text = data[i, j];
//Set font name and font size
table[j, i].TextFrame.Paragraphs[0].TextRanges[0].LatinFont = new TextFont("Times New Roman");
table[j, i].TextFrame.Paragraphs[0].TextRanges[0].FontHeight = 16;
}
//Set the alignment of the first row of the table to center
for (int i = 0; i < 5; i++)

C# Add Footers in PowerPoint Documents
Spire.Presentation enables the addition of footer, slide number, and date placeholders at the bottom of PowerPoint document pages to uniformly add the same footer content across all pages. Here are the detailed steps:
- Create a Presentation object.
- Load a PowerPoint document using the lisentation.LoadFromFile() method.
- Set Presentation.FooterVisible = true to make the footer visible and set the footer text.
- Set Presentation.SlideNumberVisible = true to make slide numbers visible, then iterate through each slide, check for the existence of a slide number placeholder, and modify the text to "Slide X" format if found.
- Set Presentation.DateTimeVisible = true to make date and time visible.
- Use the Presentation.SetDateTime() method to set the date format.
- Save the document using the Presentation.SaveToFile() method.
- C#
using Spire.Presentation;
namespace SpirePresentationDemo
{
internal class Program
{
static void Main(string[] args)
{
// Create a Presentation object
Presentation presentation = new Presentation();
// Load the presentation from a file
presentation.LoadFromFile("Sample1.pptx");
// Set the footer visible
presentation.FooterVisible = true;
// Set the footer text to "Spire.Presentation"
presentation.SetFooterText("Spire.Presentation");
// Set slide number visible
presentation.SlideNumberVisible = true;
// Iterate through each slide in the presentation
foreach (ISlide slide in presentation.Slides)
{
foreach (IShape shape in slide.Shapes)
{
if (shape.Placeholder != null)
{
// If it is a slide number placeholder
if (shape.Placeholder.Type.Equals(PlaceholderType.SlideNumber))
{
TextParagraph textParagraph = (shape as IAutoShape).TextFrame.TextRange.Paragraph;
String text = textParagraph.Text;
// Modify the slide number text to "Slide X"
textParagraph.Text = "Slide " + text;
}
}
}
}
// Set date time visible
presentation.DateTimeVisible = true;
// Set date time format
presentation.SetDateTime(DateTime.Now, "MM/dd/yyyy");
// Save the modified presentation to a file
presentation.SaveToFile("AddFooter.pptx", FileFormat.Pptx2016);
// Dispose of the Presentation object resources
presentation.Dispose();
}
}
}
C# Modify Footers in PowerPoint Documents
To modify footers in a PowerPoint document, you first need to individually inspect the shapes on each slide, identify footer placeholders, page number placeholders, etc., and then set specific content and formats for each type of placeholder. Here are the detailed steps:
- Create a Presentation object.
- Load a PowerPoint document using the Presentation.LoadFromFile() method.
- Use the Presentation.Slides[index] property to retrieve a slide.
- Use a for loop to iterate through the shapes on the slide, individually checking each shape to determine if it is a placeholder for a footer, page number, etc., and then modify its content or format accordingly.
- Save the document using the Presentation.SaveToFile() method.
- C#
using Spire.Presentation;
namespace SpirePresentationDemo
{
internal class Program
{
static void Main(string[] args)
{
// Create a Presentation object
Presentation presentation = new Presentation();
// Load the presentation from a file
presentation.LoadFromFile("Sample2.pptx");
// Get the first slide
ISlide slide = presentation.Slides[0];
// Iterate through shapes in the slide
for (int i = 0; i < slide.Shapes.Count; i++)
{
// Check if the shape is a placeholder
if (slide.Shapes[i].Placeholder != null)
{
// Get the placeholder type
PlaceholderType type = slide.Shapes[i].Placeholder.Type;
// If it is a footer placeholder
if (type == PlaceholderType.Footer)
{
// Convert the shape to IAutoShape type
IAutoShape autoShape = (IAutoShape)slide.Shapes[i];
// Set the text content to "E-ICEBLUE"
autoShape.TextFrame.Text = "E-ICEBLUE";
// Modify the text font
ChangeFont1(autoShape.TextFrame.Paragraphs[0]);
}
// If it is a slide number placeholder
if (type == PlaceholderType.SlideNumber)
{
// Convert the shape to IAutoShape type
IAutoShape autoShape = (IAutoShape)slide.Shapes[i];
// Modify the text font
ChangeFont1(autoShape.TextFrame.Paragraphs[0]);
}
}
}
// Save the modified presentation to a file
presentation.SaveToFile("ModifyFooter.pptx", FileFormat.Pptx2016);
// Dispose of the Presentation object resources
presentation.Dispose();
}
static void ChangeFont1(TextParagraph paragraph)
{
// Iterate through each text range in the paragraph
foreach (TextRange textRange in paragraph.TextRanges)
{
// Set the text style to italic
textRange.IsItalic = TriState.True;
// Set the text font
textRange.EastAsianFont = new TextFont("Times New Roman");
// Set the text font size to 34
textRange.FontHeight = 34;
// Set the text color
textRange.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Solid;
textRange.Fill.SolidColor.Color = System.Drawing.Color.LightSkyBlue;
}
}
}
}
C# Remove Footers in PowerPoint Documents
To remove footers from a PowerPoint document, you first need to locate footer placeholders, page number placeholders, date placeholders, etc., within the slides, and then remove them from the collection of shapes on the slide. Here are the detailed steps:
- Create a Presentation object.
- Load a PowerPoint document using the Presentation.LoadFromFile() method.
- Use the Presentation.Slides[index] property to retrieve a slide.
- Use a for loop to iterate through the shapes on the slide, check if it is a placeholder, and if it is a footer placeholder, page number placeholder, date placeholder, remove it from the slide.
- Save the document using the Presentation.SaveToFile() method.
- C#
using Spire.Presentation;
namespace SpirePresentationDemo
{
internal class Program
{
static void Main(string[] args)
{
// Create a Presentation object
Presentation presentation = new Presentation();
// Load the presentation from a file
presentation.LoadFromFile("Sample2.pptx");
// Get the first slide
ISlide slide = presentation.Slides[0];
// Iterate through shapes in the slide in reverse order
for (int i = slide.Shapes.Count - 1; i >= 0; i--)
{
// Check if the shape is a placeholder
if (slide.Shapes[i].Placeholder != null)
{
// Get the placeholder type
PlaceholderType type = slide.Shapes[i].Placeholder.Type;
// If it is a footer placeholder, slide number placeholder, or date placeholder
if (type == PlaceholderType.Footer || type == PlaceholderType.SlideNumber || type == PlaceholderType.DateAndTime)
{
// Remove it from the slide
slide.Shapes.RemoveAt(i);
}
}
}
// Save the modified presentation to a file
presentation.SaveToFile("RemoveFooter.pptx", FileFormat.Pptx2016);
// Dispose of the Presentation object resources
presentation.Dispose();
}
}
}
