Not Able to fetch the data of all columns of table inside a java Application

[aqib.dar]

Hello,

I am not able to extract the whole data of a table inside a java application. When I am trying to use Data Scrapping its giving me error (attached screenshot). So when I tried to loop through each cell and tried to get data using Get Text but its not able to give the data of some columns. The data seems to be hidden or something like that.
