Can I insert dynamic rows,after the columns is created dynamic in datagrid？

[cdy328]

I have dynamic columns,and defined it's "field",
but when I use the method "appendRow",then show errors:
"SyntaxError: missing : after property id",
but it works well in this method "newID0:0"
(the value of "fields[1]" is "newID0")

How can I change my codes,if I want dynamic columns and dynamic
rows in datagrid?

Thanks in advance

// create dynamic columns
columns[0].push({
   title : result.operatorUserName,
   // define "field" here,and later,I put it to fields[]
   field : "newID" + i,
   width : 90
});

// append dynamic rows
for(var m=0; m<items.length; m++){
   $('#id_list_query').edatagrid(
   'appendRow',{
      //"SyntaxError: missing : after property id"
      fields[1]:0
      // bug,it works well when use "newID0:0"
   });
}
