If you're asking about creating an HTML table from CSV data, this is what you want:

d3.csv(data.csv, function(data) {

    // the columns you'd like to display

    var columns = [name, age];



    var table = d3.select(#container).append(table),

        thead = table.append(thead),

        tbody = table.append(tbody);



    // append the header row

    thead.append(tr)

        .selectAll(th)

        .data(columns)

        .enter()

        .append(th)

            .text(function(column) { return column; });



    // create a row for each object in the data

    var rows = tbody.selectAll(tr)

        .data(data)

        .enter()

        .append(tr);



    // create a cell in each row for each column

    var cells = rows.selectAll(td)

        .data(function(row) {

            return columns.map(function(column) {

                return {column: column, value: row[column]};

            });

        })

        .enter()

        .append(td)

            .text(function(d) { return d.value; });

});

Check out the working example. If you're copying that code, you'll need to update the tabulate() function so that it either selects an existing table or a different container (rather than #container), then you can use it with CSV data like so:

d3.csv(path/to/data.csv, function(data) {

  tabulate(data, [name, age]);

});
