change colors of table with javascript

Question

I\'m trying to study for my exam and I thought I was doing this right... I want to change the color of the table (font or background) depending on which cell you click I thought

Answer 1

Change getLementbyId and getElementbyId to getElementById and change font.color to color.

        function changeFont(color){
            document.getElementById("miTabla").style.color = color;
        }
        function changeBack(color){
             document.getElementById("miTabla").style.backgroundColor = color;
        }

changeFont might also be more appropriately named changeForeground.
