jQuery Grid Plugin - jqGrid

Hello,

I am new to Jqgrid. How do i format "value" below?. When the value is 0 to 0.00 , jqgrid is displaying it as empty when value is 0.

How to check whether the value is zero or empty ?

Snippet

groupingView: {

                groupField: ["column1", "Column2"],
                groupColumnShow: [false, false],
                showSummaryOnHide: true,
                groupSummary: [true],
                groupText: ['', '{0}<span class="GroupFormat"> {value} </span>'] 
            },

 

Appreciate all your help

 

Thanks
