Fixed row and column in HTML with CSS + JavaScript

You cannot achieve the fixed row and column with HTML + CSS. You need the Javascript as well.






Below is the HTML, CSS and Javasript that accomplished the fixed row and column.

 <html lang="en">

<head>
    <script src="js/jquery-1.7.js" type="text/javascript"></script>
    <script type="text/javascript">
        function on_y_scroll(e) {
            var t = $('.tb_cells').scrollTop();
            var l = $('.tb_cells').scrollLeft();

            $('.r_headers').scrollTop(t);
            $('.c_headers').scrollLeft(l);

            console.log('left=' + l.toString() + ',top=' + t.toString());
        }
        $(document).ready(function () {
            $('.tb_cells').scroll(on_y_scroll);
        });
    </script>

    <style>
        .tb {
            background-color: darkgray;
            width: 600px;
            height: 250px;
        }
      
        /* the full row and partial should be hidden */
        .max_row_width {
            width: 500px;
        }
        /* the data row to be partially display on the screen*/
        .max_data_width {
            width: 420px;
        }
        /* the data row height */
        .row_height {
            height: 30px;
        }
        /* the column header height */
        .row0_height{
            height:40px;
        }

        /* for column zero*/
        .cell0 {
            width: 100px;
            background-color: red;
        }

        .tb_col0 {
            float: left;
        }

        .r_headers {
            height: 140px; /*this is the height of 200px (tb_data.height) - 40 (cell0) - 20 (scrollbar) */
            overflow: hidden;
        }

        .row_header {
            background-color: #0094ff;
        }

        /* for row zero */
        .c_headers {
            width: 400px;
            overflow: hidden;
        }

        .col_header {
            width: 100px;
            float: left;
            background-color: green;
            color: white;
        }

        .tb_row0 {
            clear: both;
        }

        /* for data cell */

        .tb_data {
            float: left;
            height: 200px;
            overflow: hidden;
            overflow-x: hidden;
            background-color: yellow;
        }

        .tb_cells {
            float: left;
            height: 160px; /*this is the height of 200px (tb_data.height) - 40 (cell0) - 20 (scrollbar) */
            overflow: hidden;
            overflow-y: auto;
            overflow-x: auto;
            background-color: mediumaquamarine;
        }

        .tb_row {
            clear: both;
        }

        .cell_col {
            width: 100px;
            float: left;

            /* user defined style for the cell content */
            box-sizing: border-box;
            padding-left: 5px;
            padding-right: 5px;
            text-overflow: clip;
            white-space: nowrap;
            overflow: hidden;
        }
    </style>
</head>
