# Handsontable

a minimalistic Excel-like data grid editor for HTML, JavaScript & jQuery

## Array, object and function data sources

This page shows how to use Handsontable with various data sources:

- array data source
- array data source (with hidden columns)
- object data source
- object data source (nested, with column mapping)
- object data source (custom data schema)
- function data source and schema (to reach where arrays and objects can't reach)

Please take note that Handsontable will change the original data source. More about this here: Understanding binding as reference.

## Array data source

Most of the people use array of arrays data source with Handsontable.

## Array data source (with hidden columns)

Let's say, you want the same data source, but without the Kia column.

## Object data source

With version 0.7.0, comes possibility to use array of objects data source.

## Object data source (nested, with column mapping)

Some people have nested objects. They can also be used at the data source with a little bit of column mapping.

The mapping is done using the columns option.

## Object data source (custom data schema)

When you use object data binding, Handsontable needs to know the data structure to create when you add a new row.

If your data source contains at least one row, Handsontable will figure out the data structure based on the first row.

In case you want to start with an empty data source, you will need to provide the dataSchema option that contains the data structure for any new row added to the grid.

The below example shows custom data schema with an empty data source:

## Function data source and schema (to reach where arrays and objects can't reach)

If your dataSchema is actually a constructor of an object that doesn't directly expose its members, like a Backbone.js model, you can specify functions for the data member of each columns item.

The below example shows a small example of using such objects:
