When creating a new table in PowerPoint, the rows and columns are evenly distributed by default. As you insert data into the table cells, the row heights and column widths will be automatically adjusted to fit with the contents. To make the table nicely organized, you may want to re-distribute the rows and columns. This article demonstrates how to accomplish this task 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
Distribute Table Rows and Columns
The following are the steps to distribute table rows and columns evenly in PowerPoint.
- Create a Presentation object, and load the sample PowerPoint document using Presentation.LoadFromFile() method.
- Get the first slide through Presentation.Slides[0] property.
- Loop through the shapes in the first slide, and determine if a certain shape is a table. If yes, convert the shape to an ITable object.
- Distribute the table rows and columns using ITable.DistributeRows() method and ITable.DistributeColumns() method, respectively.
- Save the changes to another file using Presentation.SaveToFile() method.
- C#
- VB.NET
using Spire.Presentation; namespace DistributeRowsAndColumns { class Program { static void Main(string[] args) { //Create a Presentation instance Presentation presentation = new Presentation(); //Load the PowerPoint document presentation.LoadFromFile(@"C:\Users\Administrator\Desktop\Table.pptx"); //Get the first slide ISlide slide = presentation.Slides[0]; //Loop through the shapes for (int i = 0; i < slide.Shapes.Count; i++) { //Determine if a shape is table if (slide.Shapes[i] is ITable) { //Get the table in the slide ITable table = (ITable)slide.Shapes[i]; //Distribute table rows table.DistributeRows(0, table.TableRows.Count-1); //Distribute table columns table.DistributeColumns(0, table.ColumnsList.Count-1); } } //Save the result to file presentation.SaveToFile("DistributeRowsAndColumns.pptx", FileFormat.Pptx2013); } } }
Imports Spire.Presentation Namespace DistributeRowsAndColumns Class Program Shared Sub Main(ByVal args() As String) 'Create a Presentation instance Dim presentation As Presentation = New Presentation() 'Load the PowerPoint document presentation.LoadFromFile("C:\Users\Administrator\Desktop\Table.pptx") 'Get the first slide Dim slide As ISlide = presentation.Slides(0) 'Loop through the shapes Dim i As Integer For i = 0 To slide.Shapes.Count- 1 Step i + 1 'Determine if a shape is table If TypeOf slide.Shapes(i) Is ITable Then 'Get the table in the slide Dim table As ITable = CType(slide.Shapes(i), ITable) 'Distribute table rows table.DistributeRows(0, table.TableRows.Count-1) 'Distribute table columns table.DistributeColumns(0, table.ColumnsList.Count-1) End If Next 'Save the result to file presentation.SaveToFile("DistributeRowsAndColumns.pptx", FileFormat.Pptx2013) End Sub End Class End Namespace
