Displays tabular data as a table.

This function takes one mandatory argument data , which must be an array or an object, and one additional optional parameter columns .

It logs data as a table. Each element in the array (or enumerable property if data is an object) will be a row in the table.

The first column in the table will be labeled (index) . If data is an array, then its values will be the array indices. If data is an object, then its values will be the property names. Note that (in Firefox) console.table is limited to displaying 1000 rows (first row is the labeled index).

Collections of primitive types

The data argument may be an array or an object.

// an array of strings console.table(["apples", "oranges", "bananas"]);

// an object whose properties are strings function Person(firstName, lastName) { this.firstName = firstName; this.lastName = lastName; } var me = new Person("John", "Smith"); console.table(me);

Collections of compound types

If the elements in the array, or properties in the object, are themselves arrays or objects, then their elements or properties are enumerated in the row, one per column:

// an array of arrays var people = [["John", "Smith"], ["Jane", "Doe"], ["Emily", "Jones"]] console.table(people);

// an array of objects function Person(firstName, lastName) { this.firstName = firstName; this.lastName = lastName; } var john = new Person("John", "Smith"); var jane = new Person("Jane", "Doe"); var emily = new Person("Emily", "Jones"); console.table([john, jane, emily]);

Note that if the array contains objects, then the columns are labeled with the property name.

// an object whose properties are objects var family = {}; family.mother = new Person("Jane", "Smith"); family.father = new Person("John", "Smith"); family.daughter = new Person("Emily", "Smith"); console.table(family);

Restricting the columns displayed

By default, console.table() lists all elements in each row. You can use the optional columns parameter to select a subset of columns to display:

// an array of objects, logging only firstName function Person(firstName, lastName) { this.firstName = firstName; this.lastName = lastName; } var john = new Person("John", "Smith"); var jane = new Person("Jane", "Doe"); var emily = new Person("Emily", "Jones"); console.table([john, jane, emily], ["firstName"]);

Sorting columns

You can sort the table by a particular column by clicking on that column's label.
