## ListObject.UpdateColumnName method

Updates all list columns' name to cells in the table.

```csharp
public void UpdateColumnName()
```

### Remarks

The value of the cells in the header row of the table must be same as the name of the ListColumn; Cell.PutValue do not auto modify the name of the ListColumn for performance.

### Examples

```csharp
using System;
using Aspose.Cells;

namespace AsposeCellsExamples
{
    public class ListObjectMethodUpdateColumnNameDemo
    {
        public static void Run()
        {
            // Create a workbook
            Workbook wb = new Workbook();
            Worksheet ws = wb.Worksheets[0];

            // Create a table/list object
            var listObject = ws.ListObjects[ws.ListObjects.Add(3, 3, 6, 6, true)];
            
            // Populate some data in the table
            for (int r = 0; r < 3; r++)
            {
                for (int c = 0; c < 3; c++)
                {
                    if (c > 0)
                        ws.Cells[listObject.StartRow + r, listObject.StartColumn + c].PutValue(r + c);
                    else
                        ws.Cells[listObject.StartRow + r, listObject.StartColumn + c].PutValue("");
                }
            }

            // Update column names (will set default names like Column1, Column2 etc.)
            listObject.UpdateColumnName();

            // Save the workbook
            wb.Save("output.xlsx");

            // Verify the column name was updated
            Console.WriteLine("First column name: " + ws.Cells[listObject.StartRow, listObject.StartColumn].StringValue);
        }
    }
}
```
