})
table = new JSONTableEditor("#foobar", {
    maxColumns: 5,
    maxRows: 20,
    formatOptions: [
      {
        type: 'button',
        name: 'bold',
        innerHTML: 'Bold'
      },
    ]
  })

[
  {
    type: 'button',
    name: 'bold',
    innerHTML: 'Bold'
  },
  {
    type: 'button',
    name: 'italic',
    innerHTML: 'Italic'
  },
  {
    type: 'radio',
    name: 'align',
    options: ['left', 'center', 'right']
  }
]

More info on formatOptions

formatOptions is an object which determines the buttons for formatting each cell.
There can be two types of formatOptions

  1. button
{
  type: 'button',
  name: 'bold',
  innerHTML: 'Bold'
}

This will add a button named bold in format buttons.
Button click will add true to active cell's format data under key bold.
You can add multiple button types and any name based on your format need, use your imagination.
Button click will also add a class named jt-cell-bold to active cell.
CSS for some of the classes is written, if you use some other name you may have to write css for that class.
innerHTML is for button's innerHTML.

  1. radio
{
  type: 'radio',
  name: 'align',
  options: ['left', 'center', 'right']
}

This will add three buttons left, center, right in format buttons.
These will behave like radio buttons and only one will be active at a time.
If center is active it will add center to active cell's format data under key 'align'.
You can add multiple radio types and any number of options based on your format need, use your imagination.
If center is active it will also add a class named jt-cell-center to active cell.
CSS for some of the classes is written, if you use some other options you may have to write css for that class.
