1. Insert Table

Step one: Create a PowerPoint document

  Presentation ppt = new Presentation ();   Ppt. Slidesize.type = slidesizetype.screen16x9;

Step two: Initialize a itable instance and specify the position, number of rows and columns, row height, and column width

Double[] widths = new double[] {[n   ], []] Double[] Heights = new double[] {A, a, a, A/n};   ITable table = ppt. Slides[0]. Shapes.appendtable (widths, heights);

Step three: Set the built-in format for the table

Table. Stylepreset = Tablestylepreset.lightstyle1accent2;

Step four: Declare and initialize a string[,] array

string[,] data = new string[,]{   {"Rank", "name", "Sales", "Return Amount", "Work Number"},   {"1", "Libiao", "18270", "18270", "0011"},   {"2", "Li Na", "18105", "18105", "0025"},   {"3", "Zhang Li", "17987", "17987", "0008"},   {"4", "Huang Yan", "17790", "17790", "0017"},};

Step Six: Save the document

Ppt. SaveToFile ("CREATE table. pptx", fileformat.pptx2010);

After completing the operation, get the following PPT document effect

2. Delete Table rows and columns

Step One: Initialize a presentation instance and load a PowerPoint document

Presentation ppt = new Presentation ();   Ppt. LoadFromFile (@ "C:\Users\Administrator\Desktop\ create table. pptx");

Step two: Get the table on the first slide

ITable table = null;   foreach (IShape shape in ppt. Slides[0]. Shapes)   {    if (Shape is ITable)    {     table = (ITable) shape;

Step Three: Delete rows fourth and fourth

Table. Columnslist.removeat (3, false;     Table. Tablerows.removeat (4, false;

Step four: Save the document

Ppt. SaveToFile ("Delete rows and columns. pptx", fileformat.pptx2010);

3. Delete a table

Step One: Initialize a presentation instance and load a PowerPoint document

Presentation ppt = new Presentation ();   Ppt. LoadFromFile (@ "C:\Users\Administrator\Desktop\ create table. pptx");

Step Two: Initialize a list object with an element type of IShape

list<ishape> tableshapes = new list<ishape> ();

Step three: Get all the table graphics on the first slide and add to the list

foreach (IShape shape in ppt. Slides[0]. Shapes)   {    if (Shape is ITable)    {     tableshapes.add (shape);    }   }

Step four: Remove the first table graphic from a slide

Ppt. Slides[0]. Shapes.remove (Tableshapes[0]);

Step Five: Save the document

Ppt. SaveToFile ("delete table. pptx", fileformat.pptx2010);
