Here it is: https://jsfiddle.net/zww557sh/1/

    function ascii_table(array, header) {
        if (!array.length) {
            return '';
        }
        var lengths = array[0].map(function(_, i) {
            var col = array.map(function(row) {
                if (row[i] != undefined) {
                    return row[i].length;
                } else {
                    return 0;
                }
            });
            return Math.max.apply(Math, col);
        });
        array = array.map(function(row, r) {
            // let's split the table cells to lines
            var cols = row.map(function(item, i){
              return item.split("\n")
            });
            // and calculate the max column-height in this row
            var maxH = (cols.reduce(function(i,j){return i.length > j.length ? i : j})).length;

            // here we manually build the string that will represent
            // this row of the table, including the "multi-line" cells
            var rowStr = "";
            // loop until the maximum cell height in this row
            for (h=0;h0) rowStr += " | ";
                // item is the h'th in column c, but it might
                // be non existing, then we use ""
                var item = cols[c][h] || "";
                var size = item.length;
                // here we use the same padding
                if (size < lengths[c]) {
                  item += new Array(lengths[c]-size+1).join(' ');
                }
                rowStr += item;
              }
              rowStr += " |";
              if (h

Output:
