To use the library, either Import the module or load it as a script.

You will need to create a new instance of the module and pass in a few parameters:

var table = new BigGrid({
    mount: '', //DOM element or queryselector string that tells us where to draw the table - required
    data: [[]], //Array of arrays containing the information that will be rendered - required
    rows:[{ // Array containing the row information
        height: // height of the row in px
    }], 
    columns:[{ // Array containing the column information
        width: // width of the column in px
    }], 
    renderer: function(rowId, columnId, value){ // Function that is called to allow custom painting of the cell
        {
            class: '', // custom class applied to this cell value
            style: {}, // custom style applied to this cell value. This may get overwritten by mandatory positioning styles
            title: '', // custom title applied to this cell value
            content: '' //custom HTML to render
        }
    },
    scroll: function(){} // Function that is called after the view is scrolled,
    resized: function(){} // Function that is called after the view is resized
})
