You can set the height of the table with the .height(css) method on the TableGenerator class, prior to render

//-- fetch the dataset
utils.datasets.fetch('cars.json').then(results => cars = results);

//-- render the table with a specific height (defaults to `50vh`)
utils.table(cars)
  .height('300px')
  .render();
