defaultColumnWidth property Null safety
final
How to determine with widths of columns that don't have an explicit sizing algorithm.
Specifically, the defaultColumnWidth is used for column i if
columnWidths[i] is null. Defaults to FlexColumnWidth, which will
divide the remaining horizontal space up evenly between columns of the
same type TableColumnWidth.
A Table in a horizontal ScrollView must use a FixedColumnWidth, or an IntrinsicColumnWidth as the horizontal space is infinite.
Implementation
final TableColumnWidth defaultColumnWidth;
