Delete Column in Table

[elcade00]

Hello Community!
Reading the How-to-Remove-Row-or-Column-in-Table document, I can't figure out how to delete an specific column in a slide with multiple tables.

For example: Delete Column 2 in Table 3.

Could you please help me?

Thank you!

Hello Simple.Li! Thank you for your help.

However, this code deletes all the second columns in all tables in the slide.
In my case I need to delete an specific column in an specific table.

For example, under certain conditions I need to delete the second column in the table 3.

See attachment.

Hello Walter Rios,

Thanks for your message. You can delete an specific column in an specific table by referring to my code below. Welcome to ask again.

Code: Select all

using Spire.Presentation;

namespace WinFormsApp4
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        public static int TestComparison(ITable a,ITable b)
        {
            float ax = a.Left;
            float ay = a.Top;
            float bx = b.Left;
            float by = b.Top;

            if (ay < by)
            {
                return -1;
            }else if (ay > by)
            {
                return 1;
            }
            else
            {
                return ax<bx ? -1 : 1;
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //Create a PPT document
            Presentation presentation = new Presentation();
            presentation.LoadFromFile(@"G:\Test\EN.pptx");

            //Get the table in PPT document
            ITable table = null;

            List<ITable> tableShapes = new List<ITable>();

            foreach (IShape shape in presentation.Slides[0].Shapes)
            {
                if (shape is ITable)
                {

                    table = (ITable)shape;
                    tableShapes.Add(table);
                   
                }
            }

            Comparison<ITable> comparison = TestComparison;
            tableShapes.Sort(comparison);
            tableShapes[2].ColumnsList.RemoveAt(1, false);

            presentation.SaveToFile("RemoveRowsAndColumns_result.pptx", FileFormat.Pptx2010);

        }
    }
}
