In a DataGrid with both buttons and text columns, adding buttons disrupts the vertical alignment of text in DataGridTextColumns, causing it to no longer be vertically centered. To fix this, I currently convert DataGridTextColumns into DataGridTemplateColumns with a TextBlock and set the VerticalAlignment there. Is there an easier way to resolve this issue without transforming each column
