i want to do the following things to the grid:

Freeze columns InvoiceNo, Date and have other columns to the right scroll horizontally
i need to set individual cell colors to colors that matches certain conditions

( A.) Color the Amount columns cells who has a value 0.00 to 'red'. This means the code shoudl find all cells with value 0.00 in Amount column and color those cells to 'red'

please note that i dont need the whole row to be colored in red only just those cells with that matching value

( B. ) just like above, in the total column find the cells that has a value that is greater than 300.00 and color them in yellow

how do i achieve this?

`cellattr` is the property/callback function of `colModel` (see [the documentation](http://www.trirand.com/jqgridwiki/doku.php?id=wiki:colmodel_options)) and not the option of the grid like `rowattr`. — Oleg, Nov 01 '16 at 23:28

First of all you should move the last part of your JavaScript code (where you call setGroupHeaders and setFrozenColumns) inside of $(function(){...}) block.

To set the color/background-color of rows based on the value of amount you should use rowattr:

rowattr: function (item) {
    if (item.amount == null || parseFloat(item.amount) === 0) {
        //return { "class": "ui-state-error" };
        //return { "style": "color: red" };
        return { "style": "background: red" };
    }
}

See the demo here: https://jsfiddle.net/f7yopLr0/1/. It produces the results like on the picture below

UPDATED: To change colors only the cells of amount and total columns one can use

cellattr: function (rowid, cellValue, item) {
    if (cellValue == null || parseFloat(cellValue) === 0) {
        return ' style="color:red"';
    }
}

in amount column and

cellattr: function (rowid, cellValue, item) {
    if (cellValue == null || parseFloat(cellValue) === 0) {
        return ' style="color:red"';
    }
}

in total column. See https://jsfiddle.net/f7yopLr0/2/

hi Oleg thanks for reply : ) that awesome. But Oleg i need to know if its possible to color only the cell that matches the condition NOT THE WHOLE ROW? e.g: if amount column cell has 0.00 it should be red so only the cells in the column Amount with value 0.00 should be colored in red but not their whole row. – NP Neil Footy Nov 01 '16 at 23:00
@ANP: Which cell? If you write about some cell then you should write about the column name which color/background color you need to change. I still don't know whether the color, background color or both you need to change. I posted you already references to old answers which demonstrates the usage of `rowattr` and `cellattr`. You need to use `cellattr`. See [the answer](http://stackoverflow.com/a/12180842/315935). One can set `class` or `style`, but one should use just a little another return value as in `rowattr`: one need return the string instead of object. – Oleg Nov 01 '16 at 23:07

@ANP: Look at the demo https://jsfiddle.net/f7yopLr0/2/. I hope it do what you need. See **UPDATED** part of my answer. – Oleg Nov 01 '16 at 23:21
