我的WPF数据网格存在一个小问题.问题在于数据网格，这是第一次在数据网格中加载数据时，在加载整个数据之后，它在数据网格中显示了一个很小的间隙.

然后，我单击标题数据网格的大小和数据网格的大小自行调整，差距消失了.我写的代码如下:

Hi

There is a small issue with my WPF datagrid. The problem is with the datagrid is that first time when the datagrid loaded with the data, after loading the entire data then it displays a small gap in the datagrid.

And once i click on the header of the datagrid and the datagrid resize itself and the gap disappears. The code which i have written is below:

<Border Grid.Row="4" 
                            Grid.Column="0" 
                            Grid.ColumnSpan="4"
