How to check if a column exists in Excel table using XlsIO?

ExcelEngine excelEngine = new ExcelEngine();
IApplication application = excelEngine.Excel;
 
//Loading a workbook with table.
IWorkbook workbook = application.Workbooks.Open("ExcelTable.xlsx");
 
//The first worksheet is accessed.           
IWorksheet worksheet = workbook.Worksheets[0];
IListObject table = worksheet.ListObjects[0]; 
                                                
string[] columns = { "Name", "Time", "Location" };
 
//Passing the table object and column names to check whether it exists.
if (IsFieldExist(table, columns))
{
    MessageBox.Show("All the column names exists in the table.");
}
else
{
    MessageBox.Show("Some of the column names does not exist in the table.");
}
 
//Close the workbook.              
workbook.SaveAs("OutputFile.xlsx");
 
//Close the workbook and dispose the engine.
workbook.Close();
excelEngine.Dispose();
 
private bool IsFieldExist(IListObject table, string[] columnNames)
        {
            IList<IListObjectColumn> tableColumn = table.Columns;
            IList<string> columnNamesList = columnNames.ToList<string>();
 
            foreach (IListObjectColumn column in tableColumn)
            {

                {
                    columnNamesList.Remove(column.Name);
                }
            }
 
            return columnNamesList.Count == 0 ? true : false;
        }
