Convert Table to an Array

The following should do it!

var array = [];
var headers = [];
$('#dataTable th').each(function(index, item) {
    headers[index] = $(item).html();
});
$('#dataTable tr').has('td').each(function() {
    var arrayItem = {};
    $('td', $(this)).each(function(index, item) {
        arrayItem[headers[index]] = $(item).html();
    });
    array.push(arrayItem);
});

See here for jsFiddle

var table = document.getElementById( "dataTable" );
var tableArr = [];
for ( var i = 1; i < table.rows.length; i++ ) {
    tableArr.push({
        category: table.rows[i].cells[0].innerHTML,
        brandName: table.rows[i].cells[1].innerHTML,
        whenObtained: table.rows[i].cells[2].innerHTML,
        howObtained: table.rows[i].cells[3].innerHTML,
        howOftenWorn: table.rows[i].cells[4].innerHTML,
        whereMade: table.rows[i].cells[5].innerHTML,
        hasGraphic: table.rows[i].cells[6].innerHTML
    });
}
