JSON Object Array of Properties

I've been trying to figure out this particular object for quite a while and it's frustrating me endlessly so I was hoping to get it resolved here.

I have an object that looks like this:

options = {
    headers: {
        rows: [
            cols = {
                text: "Blah",
                span: 12,
                color: "#FFF"
            }
        ],
        [
            cols = {
                text: "Blah2",
                span: 8,
                color: "#FFF"
            }
            cols = {
                text: "Blah2",
                span: 4,
                color: "#FFF"
            }
        ]
    }
}

With the intended result being an object that can be used to populate header rows above a table using a combination of the text, span, and color properties (with a few additions for later) to customize styling it properly.

I'm going for:

var te开发者_运维问答xt = options.headers.rows[x].cols[y].text;

Such that a nested loop can generate out the headers. Any help is appreciated!

var options = {
    headers: {
        rows: [ // Array
        { // row: 0
            cols: [ // Array
            { // col: 0
                text: "Blah",
                span: 12,
                color: "#FFF"
            },
            { // col: 1
                text: "Blah2",
                span: 8,
                color: "#FFF"
            },
            { // col: 2
                text: "Blah2",
                span: 4,
                color: "#FFF"
            }]
        },
        { // row: 1
            cols: [ // Array
            { // col: 0
                text: "Blah",
                span: 12,
                color: "#FFF"
            },
            { // col: 1
                text: "Blah2",
                span: 4,
                color: "#FFF"
            }]
        }]
    }
