Added the new Table Widget

- Added `Table.zig` under the `src/widgets` directory and `widgets.zig` module.
- Created the `drawTable()` function to draw a Table to the provided parent Window based on the provided ArrayList.
- Created the `TableContext` struct to manage state and attributes for the `drawTable()` function.
