minIntrinsicWidth method Null safety
The smallest width that the column can have.
cells argument is an iterable that provides all the cells
in the table for this column. Walking the cells is by definition
O(N), so algorithms that do that should be considered expensive.
containerWidth argument is the
maxWidth of the incoming
constraints for the table, and might be infinite.
double minIntrinsicWidth(Iterable<RenderBox> cells, double containerWidth);
