The default text alignment

If you do not specify a column’s Width property explicitly, its value is automatically calculated based on the TreeList’s total width, other column widths, borders, and cell spacing. For more information on how this algorithm works in different scenarios, refer to the following topic: Column Layout Specifics in Blazor TreeList.

The TreeList component can automatically collapse columns with unspecified widths if there is not enough space to display all columns. To prevent a column from collapsing, set its MinWidth property to a non-zero value.
