I have a Handsontable table filled with data and already rendered

After checking the cells, I have located a couple of cells of interest and would like to color them - is there a good way to do this using the Handsontable code? 

Please note this is after loading and rendering the table

Edit: 

The table is rendered with basic options:

```
$container.handsontable({
    startRows: 8,
    startCols: 6,
    rowHeaders: true,
    colHeaders: true,
    minSpareRows: 1,
    minSpareCols: 1,
    //contextMenu: false,
    cells: function (row, col, prop) {
    }
  });

```

And the data is loaded via Ajax, decode\_file.php reads an excel sheet and returns data as JSON:

```
  $.ajax({
      url: "decode_file.php",
      type: 'GET',
      success: function (res) {
        handsontable.loadData(res.data);
        console.log('Data loaded');
      },
      error: function (res) {
        console.log("Error : " + res.code);
      }
    });

```

After loading the data, the user clicks a "Process" button and the code looks for a cell with the text "Hello world". Let's say the code finds the text "Hello World" in cell **row 4/col 5** and changed the background color of cell **row 4/col 5** to **red**

The homepage provides a good example for your purpose:

<http://handsontable.com/demo/renderers.html>

Just modify the condition (in this case upper/left corner).

```
cells: function (row, col, prop) {
  if (row === 0 && col === 0) {
    return {type: {renderer: greenRenderer}};
  }
}

```

and you're done.
One a bit strange method that I'm using, and it actually fast and works fine:

```
afterRender: function(){
    render_color(this);
}

```

ht is the instance of the handsontable, and render\_color:

```
function render_color(ht){
  for(var i=0;i<ht.countRows();i++){
    for(var p=0;p<ht.countCols();p++){
      cell_color = "#000";
      font_color = "#fff";
      $(ht.getCell(i,p)).css({"color": font_color, "background-color": cell_color})
    }
  }
}

```
