I had this problem too. Actually, I read this page tried and tried again. But could not get the data shown in json format.

Finally, I found this page:http://www.comanswer.com/question/jqgrid-with-json-data-renders-table-as-empty.

The reason that the data can not be shown is that our json format is not strict enough.

reference here: http://simonwillison.net/2006/…..t/11/json/

{page: '1', records: '6', rows: [{cell:['X-RAY', '46190', '1144', '2127', '17', '49479'], id: '1'},{cell:['NMR', '6846', '849', '146', '6', '7847'], id: '2'},{cell:['ELECTRON MICROSCOPY', '165', '16', '59', '0', '240'], id: '3'},{cell:['HYBRID', '13', '1', '1', '1', '16'], id: '4'},{cell:['other', '108', '4', '4', '9', '125'], id: '5'},{cell:['Total', '53322', '2014', '2337', '33', '57707'], id: '6'}],total: '1'}

maybe, you should replace the “ by “ if you place the string above between the ” “

PS: I am sorry for some grammer error, my english is pool. Thanks!
