Preventing empty columns when exporting to word document

Question

I want to export the  columns I pulled into the datagridview with Checkbox to Word. However, it also exports the hidden columns to Word that I have not checked with the checkboxes and that do not appear in the datagridview. I want to export only selected columns as shown in the image. What is the solution?

 public void Export_Data_To_Word(DataGridView DGV, string filename)
 {
     if (File.Exists(filename))
     {
         File.Delete(filename);

     oWord.WindowState = Word.WdWindowState.wdWindowStateMaximize;

     if (DGV.Rows.Count != 0)
     {
         int RowCount = DGV.Rows.Count;
         int ColumnCount = DGV.Columns.Count;
         Object[,] DataArray = new object[RowCount + 1, ColumnCount + 1];

         //add rows
         int r = 0;
         for (int c = 0; c <= ColumnCount - 1; c++)
         {
             if (DGV.Columns[c].Visible) // Check if the column is visible
             {
                 for (r = 0; r <= RowCount - 1; r++)
                 {

                     DataArray[r, c] = DGV.Rows[r].Cells[c].Value;
                 } //end row loop
