I want to add a summary row to my grid but the grin line does not work on my grid. I can see the summary row but There is no numerical data. Please tell me how to solve it.

  $ ("# sale list"). JqGrid ({Data: "Jason", JasonReader: {Root: "Rows", Page: "Page", Total: "Total", Record: "Records", Repeats: Wrong, Id: "0"}, URL: "/ Sales Report / Get Datated Seal List? Start Date" "$$" ("#txtstartDate"). Val () + "& amp; ['Date', 'Name', 'Price', 'Tax'] , Colomodel: [{Name: 'reg_date', width: 100, formatter: getTime}, {name: 'name', width: 80}, {name: 'PRICE', index: 'PRICE', width: 80, aligned Do: "right" formatter: 'number', formatoptions: {decimal: 2}}, {name: 'tax', index: 'tax', width: 80, align: Correct ", formatter: 'number', formatoptions: {decimalplace: 2}}, height: 450, line number: 10, type name: 'reg_date', see records: correct, autovoth: true, to shrink: wrong , Line list: [10, 20, 30], pager: '# pager1', footro: true, userdataonfooter: true, rownumbers: true,});
