var Table = require('./cli-table'); // instantiate var table = new Table({ head: ['TH 1 label', 'TH 2 label'] , colWidths: [20, 20] }); // table is an Array, so you can `push`, `unshift`, `splice` and friends table.push( ['First value', 'Second value with overlength'] , ['First value', 'Second value'] ); console.log(table.toString());
