A table is a 2D string array so for both your analog and digital signals, you need to convert them to strings. On the string palette, you can use format into string to convert numbers to string representation or booleans to TRUE/FALSE strings. On the String/Number Conversion sub-palette, you could also use Number to Fractional String. This is polymorphic so if your analog values are in an array, you can just wire that to the function instead of uing Format Into String inside of a for loop.
