Hello

https://help.syncfusion.com/file-formats/pdf/working-with-tables#creating-a-simple-table

but Im getting this error when it gets to the pdfLightTable.Draw part:

Hi Ara, 

Sorry for the inconvenience caused, 

The DataTable is not supported as data source in PDF light table in Xamarin forms platform. We suggesting you to use IEnumerable as Data source in Xamarin forms as provided in the code snippet. Please find the below code snippet for more details : 
           void DrawTable() 
{ 
            //List of Columns 
            List<Customer> collection = new List<Customer>(); 
            Customer customer = new Customer(); 
 
            //Add Row values 
            customer.Name = "Jhone"; 
            customer.RollNumer = "44"; 
            customer.Class = "A"; 
 
            //Add Row values 
            collection.Add(customer); 
             customer = new Customer(); 
            customer.Name = "whell"; 
            customer.RollNumer = "43"; 
            customer.Class = "B"; 
 
            //Add Row values 
            collection.Add(customer); 
             customer = new Customer(); 
            customer.Name = "Andrew"; 
            customer.RollNumer = "48"; 
            customer.Class = "C"; 
 
            collection.Add(customer); 
 
           // Create a PdfLightTable. 
            PdfLightTable pdfLightTable = new PdfLightTable(); 
            pdfLightTable.Style.ShowHeader = true; 
 
            //Assign data source. 
            pdfLightTable.DataSource = collection; 
 
            //Draw PdfLightTable. 
            pdfLightTable.Draw(page, new PointF(30, 70)); 
 
} 
 
 
  private class Customer 
        { 
            private string m_name; 
            private string m_roolNumber; 
            private string m_class; 
            public string Name 
            { 
                get 
                { 
                    return m_name;  
                } 
                set 
                { 
                    m_name = value; 
                } 
            } 
            public string RollNumer 
            { 
                get 
                { 
                    return m_roolNumber; 
                } 
                set 
                { 
                    m_roolNumber = value; 
                } 
            } 
            public string Class 
            { 
                get 
                { 
                    return m_class; 
                } 
                set 
                { 
                    m_class = value; 
                } 
            } 
        }
