Table not displaying the data for particular TAGs

We are using Ignition version 8.1.7
We are trying to display the historical data in a table. History data is already collecting and displaying in the table . Now customer is asking to add few more tags in it. When we trying to add new tags in data binding, it is not showing the data in table. The value of the new TAGs in the history is zero now.
Earlier, we have done this kind of development many times.
If we collect same data in Vision, the data is displayed.
