Add functionality for easily creating table with headers #109
Description
Currently creating a table with headers requires quite some effort.
However, it should be relatively easy to provide this functionality in the library.
At the very least some better examples could be supplied.
Here is a rather simplistic approach that works quite well:
const { table } = require('table');
const chalk = require('chalk');
function printTable(data, options) {
if (!data || !data.length) {
return;
}
options = options || {};
options.columns = options.columns || Object.keys(data[0]);
options.headerStyleFn = options.headerStyleFn || chalk.bold;
const header = options.columns.map(property => options.headerStyleFn(property));
const tableText = table([
header,
...data.map(item => options.columns.map(property => item[property]))
]);
console.log(tableText);
}
const data = [
{ firstName: 'John', lastName: 'Doe' }
];
printTable(data);
printTable(data ,{
columns: ['lastName', 'firstName']
}
);
printTable(data, {
headerStyleFn: chalk.red
});
printTable(data, {
headerStyleFn: header => chalk.bold(chalk.red(header))
});
