Build a generalized data table component in React.

Requirements:

1. Display tabular data with columns and rows.
2. Support client-side pagination (e.g., 5 or 10 rows per page).
3. Allow sorting by clicking on column headers (toggle ascending/descending).
4. Add a simple search box for filtering rows.
5. Make the component reusable by passing in data and columns as props.
6. Focus on functionality over styling.
