Introduction

Aspose.Slides also facilitates developers to add custom tables in their slides from scratch. This is one of the newest features added in Aspose.Slides since last few versions. In this topic, we will explain that how can developers create and add tables to their slides using Aspose.Slides.

 

Creating a Table from Scratch

Aspose.Slides has provided the simplest API to create tables in an easiest way. To create a table in a slide and perform some basic operations on the table, please follow the steps below:

• Create an instance of Presentation class
• Obtain the reference of a slide by using its Position
• Set Table Parameters that are required to create a table. This step is Optional
• Add a Table to the slide according to specified Table Parameters
• Set the Alternative Text of the Table that can be used to identify this table instance in the slide. This step is also Optional
• Merge first two cells of the first row of the table. This step is Optional too
• Access the Text Frame of a Cell. It's Optional
• Add some text to the Text Frame. It's also Optional
• Write the modified presentation as a PPT file

 

Example:

[C#]

 

 

//Instantiate a Presentation object that represents a PPT file

Presentation pres=new Presentation("demo.ppt");

 

 

//Accessing a slide using its slide position

Slide slide = pres.GetSlideByPosition(2);

 

 

//Setting table parameters

int xPosition=880;

int yPosition=1400;

int tableWidth=4000;

int tableHeight=500;

int columns=4;

int rows=4;

double borderWidth=2;

 

 

//Adding a new table to the slide using specified table parameters

Table table=slide.Shapes.AddTable(xPosition,yPosition,tableWidth,tableHeight,

                                columns,rows,borderWidth,Color.Blue);

 

 

//Setting the alternative text for the table that can help in future to find

//and identify this specific table

table.AlternativeText="myTable";

 

 

//Merging two cells

table.MergeCells(table.GetCell(0,0),table.GetCell(1,0));               

 

 

//Accessing the text frame of the first cell of the first row in the table

TextFrame tf=table.GetCell(0,0).TextFrame;

 

 

//If text frame is not null then add some text to the cell

if(tf!=null)

{

   tf.Paragraphs[0].Portions[0].Text="Welcome to Aspose.Slides";

}

 

 

//Writing the presentation as a PPT file

pres.Write("C:\\modified.ppt");

 

 

[VB.NET]

 

 

'Instantiate a Presentation object that represents a PPT file

Dim pres As Presentation = New Presentation("demo.ppt")

 

 

'Accessing a slide using its slide position

Dim slide As Slide =  pres.GetSlideByPosition(2)

 

 

'Setting table parameters

Dim xPosition As Integer = 880

Dim yPosition As Integer = 1400

Dim tableWidth As Integer = 4000

Dim tableHeight As Integer = 500

Dim columns As Integer = 4

Dim rows As Integer = 4

Dim borderWidth As Double = 2

 

 

'Adding a new table to the slide using specified table parameters

Table table=slide.Shapes.AddTable(xPosition,yPosition,tableWidth,tableHeight,

                                columns,rows,borderWidth,Color.Blue)

 

 

'Setting the alternative text for the table that can help in future to find

'and identify this specific table

table.AlternativeText="myTable"

 

 

'Merging two cells

table.MergeCells(table.GetCell(0,0),table.GetCell(1,0))               

 

 

'Accessing the text frame of the first cell of the first row in the table

Dim tf As TextFrame = table.GetCell(0,0).TextFrame

 

 

'If text frame is not null then add some text to the cell

If tf <> Nothing Then

   tf.Paragraphs(0).Portions(0).Text="Welcome to Aspose.Slides"

 

 

'Writing the presentation as a PPT file

pres.Write("C:\\modified.ppt")

 

 

[Java]

 

 

try

{

    //Instantiate a Presentation object that represents a PPT file       

    Presentation pres = new Presentation(new FileInputStream(new File("demo.ppt")));

 

 

    //Accessing a slide using its slide position

    Slide slide = pres.getSlideByPosition(2);

 

 

    //Setting table parameters

    int xPosition=880;

    int yPosition=1400;

    int tableWidth=4000;

    int tableHeight=500;

    int columns=4;

    int rows=4;

    double borderWidth=2;

 

 

    //Adding a new table to the slide using specified table parameters

    Table table=slide.getShapes().addTable(xPosition,yPosition,tableWidth,tableHeight,

                                columns,rows,borderWidth,java.awt.Color.Blue);

 

 

    //Setting the alternative text for the table that can help in future to find

    //and identify this specific table

    table.setAlternativeText("myTable");

 

 

    //Merging two cells

    table.mergeCells(table.getCell(0,0),table.getCell(1,0));               

 

 

    //Accessing the text frame of the first cell of the first row in the table

    TextFrame tf=table.getCell(0,0).getTextFrame();

 

 

    //If text frame is not null then add some text to the cell

    if(tf!=null)

    {

      tf.getParagraphs().get(0).getPortions().get(0).setText("Welcome to Aspose.Slides");

    }

 

 

    //Writing the presentation as a PPT file

    pres.write(new FileOutputStream(new File("modified.ppt")));

}

catch(Exception ex)

{

    System.out.println(ex.toString());

}

The above code snippet adds a table to the slide as shown below:
