How to add a row to an existing table in PowerPoint documents
Spire.Presentation is a powerful and standalone .NET component which designed for developers to operate the PowerPoint documents in C# and VB.NET. Spire.Presentation enable developers to insert a new table, remove rows or columns in an existing table, and remove the whole table from the presentation slides. This article we will show you how to add a row to an existing table in presentation slide by using C# code.
Step 1: Create Presentation instance and load file.
Presentation ppt = new Presentation();
ppt.LoadFromFile("table.pptx");
Step 2: Get the table within the PowerPoint document.
ITable table = ppt.Slides[0].Shapes[4] as ITable;
Step 3: Add a new row into the PowerPoint table and set the data for the cells in the new row.
//Get the first row TableRow row = table.TableRows[0]; //Clone the row and add it to the end of table table.TableRows.Append(row); int rowCount = table.TableRows.Count; //Get the last row TableRow lastRow = table.TableRows[rowCount - 1]; //Set new data of the first cell of last row lastRow[0].TextFrame.Text = " The first cell"; //Set new data of the second cell of last row lastRow[1].TextFrame.Text = " The second cell";
Step 4: Save the document and preview it.
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");

How to Apply Built-in Style to PowerPoint Table in C#, VB.NET
Built-in table styles are predefined formatting options that can be quickly applied to any table, greatly enhancing its appearance and readability. As same as MS PowerPoint, Spire.Presentation provides such a feature to give your table a professional look by applying a certain built-in table style. This article presents how this purpose can be achieved using Spire.Presentation with C#, VB.NET.
As we can see from below picture, plain tale is not that attractive before applying any style.
Code Snippet for Applying Table Style:
Step 1: Create an instance of presentation and load the test file.
Presentation ppt = new Presentation("test.pptx", FileFormat.Pptx2010);
Step 2: Get the table from presentation slide.
ITable table = ppt.Slides[0].Shapes[1] as ITable;
Step 3: Choose one table style from TableStylePreset and apply it to selected table.
table.StylePreset = TableStylePreset.MediumStyle2Accent2;
Step 4: Save the file.
ppt.SaveToFile("Result.pptx", FileFormat.Pptx2010);

How to fill the table cell with color in PowerPoint document in C#
A table provides a visual grouping of information and gives more convenience for writer to modify and query data in table. In particular when you have a table with colorful cells, your document would be more attractive. With the help of Spire.Presentation, developers can easily add tables and set table styles in PowerPoint document. This tutorial shows you how to fill the table cells with color in C#.
Step 1: Create a presentation document and load the file from disk.
Presentation presentation = new Presentation();
presentation.LoadFromFile("sample.pptx");
Step 2: Fill the table cell with color. You can fill all the cells or only fill one single row of cell in table with color.
foreach (TableRow row in table.TableRows)
{
foreach (Cell cell in row)
{
cell.FillFormat.FillType = FillFormatType.Solid;
cell.FillFormat.SolidColor.Color = Color.Green;
}
}
Step 3: Save the presentation documents to file.
presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);

Merge table cells on PowerPoint Slide
A table, as a great way to present data into groups, always plays an important role in any type of electronic documents. A well formatted table must contains larger or smaller cells without influencing the entire row or colum - and that's something that can be easily achieved by merging or splitting cells in your existing table.
In the next section, we will introduce you how to merge cells on en existing table which is embedded on a PowerPoint slide using Spire.Presentation for .NET. By convention, we need to download and install Spire.Presentation first, add its dll as a reference in you Visual C# or VB.NET project.
Assume you got a sample PPT file which contains a table like this, obviously you can merge cell 2 and cell 3 in the first column to display the account information more clearly.
How to achieve this programmatically using Spire.Presentation?
Step 1: Create a PPT document and load the sample file.
Presentation presentation = new Presentation();
presentation.LoadFromFile("table.pptx");
Step 2: Get the table and merge the second row and third row of the first column.
ITable table = null;
foreach (IShape shape in presentation.Slides[0].Shapes)
{
if (shape is ITable)
{
table = (ITable)shape;
table.MergeCells(table[0, 1], table[0, 2], false);
}
}
Step 3: Save and launch the file.
presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
Result:
Full code:
using Spire.Presentation;
namespace MergeCells
{
class Program
{
static void Main(string[] args)
{
// create a PPT document and load file
Presentation presentation = new Presentation();
presentation.LoadFromFile("table.pptx");
// get the table in PPT document
ITable table = null;
foreach (IShape shape in presentation.Slides[0].Shapes)
{
if (shape is ITable)
{
table = (ITable)shape;
//merge the second row and third row of the first column
table.MergeCells(table[0, 1], table[0, 2], false);
}
}
// save the document
presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
}
}

C#/VB.NET: Insert Tables in PowerPoint Presentations
Tables in PowerPoint are a powerful tool that allows you to present and organize data in a clear, concise, and visually appealing manner. By using tables, you can effectively communicate complex information to your audience, making it easier for them to understand and remember key points. In this article, you will learn how to insert a table into a PowerPoint Presentation in C# and VB.NET using Spire.Presentation for .NET.
Install Spire.Presentation for .NET
To begin with, you need to add the DLL files included in the Spire.Presentation for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Presentation
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
