Resize table only if screen is above 760px

Question

Resize table only if screen is above 760px

I would like to make a responsive table. My goal is to switch it from a table to more, as shown here . However, although it still looks like a table, I would like all the rows to have the height of the highest row.

I managed to do this work separately, but when I try to combine them, resizing distorts the table format as a list. How do I reset the initial state of a table to any resize when I go below 760 pixels?

Here is the html that I have so far:

function resizeTable(tableID){
	var tbl=document.getElementById(tableID), row=0;


	if ($(window).width() > 760) {
		var biggestRow=0, rowHeight=0;
		for (row=0; row < tbl.rows.length; row++) {     //find biggest row height
			rowHeight=parseInt(tbl.rows[row].offsetHeight);
			if (rowHeight > biggestRow) {biggestRow=rowHeight;}
		}
		for (row=0; row < tbl.rows.length; row++) {     //set all rows to biggest row height
			tbl.rows[row].style.height=biggestRow + "px";
		}
	} else {
		for (row=0; row < tbl.rows.length; row++) {     
			tbl.rows[row].style.height='auto';
		}
	}
} 

$(window).resize(function () {
	resizeTable('myTable');
});

table { 
    width: 100%; 
    border-collapse: collapse; 
}
/* Zebra striping */
.myTable tr:nth-of-type(odd) { 
    background: #eee; 
}

.myTable th { 
    background: #3F3F3F; 
    color: white; 
    font-weight: bold; 
}
td, th { 
    padding: 6px;
    border: 1px solid #ccc; 
    text-align: left; 
} 
/*
