    Moving cell values within a table

    Hello, I'm trying to move cell values within a three by three table. I have read about the 2D matrix algorithm similar. But I am moving one cell at a time with the click of a button. Is this possible with jQuery or JS? I have the following table:

    [1][2][3]
    [4][5][6]
    [7][8][9]

    and I want to click a button to move right like so:

    [4][1][2]
    [7][5][3]
    [8][9][6]

    and so on..

    this is my HTML:

    <table>
    <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    </tr><tr>
    <td>4</td>
    <td>5</td>
    <td>6</td>
    </tr><tr>
    <td>7</td>
    <td>8</td>
    <td>9</td>
    </tr>
    </table>

    <button id="moveStuff">Move!</button>

    Any help is greatly appreciated.

    Here is a quick and dirty solution, it can be done a lot better depending more details about the rules and such....In current state, it does exactly what you asked for..

    Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
            "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
        <title>Your Web Page Title</title>
        <script type="text/javascript">
            <!--
            function moveStuff() {
                //get the table which has the cells
                var vtable = document.getElementById("table_grid1");
                //get all the rows from that table
                var trows = vtable.getElementsByTagName("tr");
                var rlen = trows.length;
                //create containers to hold original values for each cell
                var prevTempCells,currTempCells;
                //loop thru each row and move cells
                for (var x = 0; x < rlen; x++) {
                    var row = trows[x];
                    var cells = row.getElementsByTagName("td");
                    currTempCells = cloneCellReturnArrayWithValues(cells);
                    if (x == 0) { //according to your rules first row and second row are handled differently
                        prevTempCells = currTempCells;
    
                        cells[1].innerHTML = prevTempCells[0];
                        cells[2].innerHTML = prevTempCells[1];
                    } else {
                        //update first cell of prev row
                        trows[x - 1].getElementsByTagName("td")[0].innerHTML = currTempCells[0]
    
                        cells[0].innerHTML = currTempCells[1]; //update first cell of current row with second cells value
                        if (x != 1) {//according to ur rules center cell in middle row is not changed
                            cells[1].innerHTML = currTempCells[2];//put 3rd cells value in second cell
                        }
                        //update 3rd cell with 3rd cell of prev row
                        cells[2].innerHTML = prevTempCells[2];
                        //reset prev container with current container
                        prevTempCells = currTempCells;
                    }
    
                }
            }
            /*
             Utility function to convert cell values into an array
             */
            function cloneCellReturnArrayWithValues(cells) {
                var arr = new Array();
                for (var x = 0; x < cells.length; x++) {
                    arr[x] = cells[x].innerHTML;
                }
                return arr;
            }
            // -->
        </script>
    </head>
    <body>
    <table id="table_grid1">
        <tr>
            <td>1</td>
            <td>2</td>
            <td>3</td>
        </tr>
        <tr>
            <td>4</td>
            <td>5</td>
            <td>6</td>
        </tr>
        <tr>
            <td>7</td>
            <td>8</td>
            <td>9</td>
        </tr>
    </table>
    
    <button id="move_stuff" onclick="moveStuff();">Move!</button>

    my variant (i think it's too messy):

    live demo - click any cell to rotate cells and also you can choose direction
