1N/A<h2>Formatting Row Data for Display</h2>

1N/A

1N/A<p>Data can be stored in one format but be displayed in a different format. For instance, prices can be stored as numbers but be displayed as "$2.99", and birthdays can be stored as date objects but be displayed as "12/9/2009".

1N/A

1N/A<p>Simple formatting can be defined with a string template on the column definition.</p>

1N/A

1N/A```

1N/AYUI().use("datatable-base", function(Y) {

1N/A var cols = ["id","name", {key:"price", formatter:"\${value}"}],

1N/A data = [

1N/A {id:"ga-3475", name:"gadget", price:6.99},

1N/A {id:"sp-9980", name:"sprocket", price:3.75},

1N/A {id:"wi-0650", name:"widget", price:4.25}

1N/A columnset: cols,

1N/A recordset: data,

1N/A caption: "Data formatting with string template"

1N/A }).render("#template");

1N/A```

1N/A

1N/A<p>When a calculation is needed, define a custom function that generates markup for the data cell. The custom formatter function receives an object with the following properties: `{tbody, tr, td, classnames, headers, rowindex, record, column, data, value}`.</p>

1N/A

1N/A```

1N/A// The custom formatter function recieves an object with the properties:

1N/A// {tbody, tr, td, classnames, headers, rowindex, record, column, data, value}

1N/Avar calculate = function (o){

1N/A var record = o.record;

1N/A return "$"+(record.getValue("price") - record.getValue("cost"));

1N/A},

<p>The DataType utility can be used to help format date objects. This example

also uses the `emptyCellValue` column configuration to supply a custom cell

value in the case of missing data.</p>

// {tbody, tr, td, classnames, headers, rowindex, record, column, data, value}
