How to get a correct row count in SAP table?

Hello,

I've been struggling to have a correct row count in my orders. Sometimes I can have from 1 to 50 items in it. I was only get row counts that includes all rows and only visible row count that can be seen on screen.

Is there any way to identify a number of rows that has data in them? Below are the references

TotalRow = session.findById("wnd[0]/usr/tabsTAXI_TABSTRIP_OVERVIEW/tabpT\01/ssubSUBSCREEN_BODY:SAPMV45A:4400/subSUBSCREEN_TC:SAPMV45A:4900/tblSAPMV45ATCTRL_U_ERF_AUFTRAG").rowCount    

VisibleRow = session.findById("wnd[0]/usr/tabsTAXI_TABSTRIP_OVERVIEW/tabpT\01/ssubSUBSCREEN_BODY:SAPMV45A:4400/subSUBSCREEN_TC:SAPMV45A:4900/tblSAPMV45ATCTRL_U_ERF_AUFTRAG").visiblerowCount
