Compare Thingworx infotable having same datashape

@Siddharth_Jhs ,

The easiest way to do this is to just iterate through the infotables and compare the columns one-by-one and then store the differences in a third infotable.

For example, if you know that the rows in the first two tables should be directly compared (i.e. you want to compare row 1 of the first table with row 2 of the second table: 

var len = myInfoTable1.getRowCount()


var params = {
 infoTableName : "InfoTable",
 dataShapeName : "MyDataShape"
};

// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(EAS.Mun.DataShape.ContactImport)
var result = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);


for(var i = 0; i < len; i++) {
 var diff1 = myInfoTable2[i].Reading - myInfoTable1[i].Reading;
 var diff2 = myInfoTable2[i].AnotherReading - myInfoTable1[i].AnotherReading;
 
 var row = new Object();
 
 row.Reading = diff1;
 row.AnotherReading = diff2;
 
 result.AddRow(row);
}
