[Feature Request] Support for ShrinkWrap / MainAxisSize.min

[Johannes5000]

Currently, when using a DataTable2 with only a few rows, the table automatically expands to fill more space than necessary. I would like an option for the table to adjust its size based on its content, using only the minimum required space when there are limited rows. This would help keep layouts compact and avoid unnecessary whitespace.

Proposed Solution:
Provide support for shrinkWrap or MainAxisSize.min so that the table height can dynamically adjust based on the number of rows displayed.
