title: Kendo grid - summary fields in a single row
body: <p>is it possible to sum fields in a row of kendo grid? I'm able to summary columns in table but not a single rows. I've set aggregation for each field but it works only for "footerTemplate". I hope my question is clear... Thanks for any help!</p>
  
  <p>Example:</p>
  
  <p>User      | Jan   | Feb   | Mar  | Sum</p>
  
  <p>John      | 1000  | 2000  | 3000 | ???</p>
  
  <p>Peter     | 1500  | 2500  | 3500 | ???</p>
  
  <p><em>footerTemplate SUM</em>       | <strong>2500</strong>  | <strong>4500</strong>  | <strong>6500</strong> | ???</p>
  
  <p>In DataSource I define aggregation and group:</p>
  
  <pre><code>aggregate: [ 
    { field: "Jan", aggregate: "sum" },
    { field: "Feb", aggregate: "sum" }, ...
  ],
  ...
  group: {field: "???",  aggregates: [ { field: "Jan", aggregate: "sum" }, { field: "Feb", aggregate: "sum" } ]}
  ...
  columns: [
    ...,
    { "field": "???", "title": "Summary", "format": "{0:n0}", "footerTemplate": "#= kendo.toString(sum, \"C\")#", "groupFooterTemplate": "#= kendo.toString(sum, \"C\")#" },
  ]
  </code></pre>
  
  <p>Thanks very much for any answer</p>
