I want to configure this type of table.
If more data comes in, one more column of C5 is created.

I want to bind it.
I need to set the PropertyPath in the column, but I don't know how to use it in the case of an array.

Column Wavelength = GridUtil.Instance.SetColumn(ColumnTypes.Text, "Wavelst", "Wavelength", new ColumnWidth() { Value = 150 });
this.xDataGrid.Columns.Add(Wavelength);
Column ABS = GridUtil.Instance.SetColumn(ColumnTypes.Text, "ABSlst", "C1", new ColumnWidth() { Value = 150 });
this.xDataGrid.Columns.Add(ABS);

List<ModelMeasureData> temp = new List<ModelMeasureData>();
foreach (var wave in this.m_Model.WaveList)
{
ModelMeasureData t = new ModelMeasureData();
t.Wavelst.Add(wave);
t.ABSlst.Add(wave);

temp.Add(t);
}

this.xDataGrid.ItemsSource = temp;

public class ModelMeasureData
{
public ModelMeasureData()
{
Wavelst = new List<float>();
ABSlst = new List<float>();
}

public List<float> Wavelst
{ get; set; }

public List<float> ABSlst
{ get; set; }

public float Wave { get; set; }
public float ABS { get; set; }

}
