Multiple console warnings due to Class Component structure

[pradeepassrr]

As React is reaching 20+ version numbering with 18+ being a stable one, existing Class components in react-base-table should be converted to Function Components to avoid the below warnings.

Warning: TableHeaderRow2: Support for defaultProps will be removed from function components in a future major release. Use JavaScript default parameters instead.

Any update about this

I've submitted PR #444 that addresses this issue — converts all 7 class components to function components with React hooks, consolidates TypeScript types, removes PropTypes, and improves type safety. Ready for review. cc @nihgwu
