Error processing Component for table

Hello,
This is an urgent query, I am stuck in designing of my dashboard. I am fairly new user to Pentaho.
I made a new Dashboard, and I completed all the layout using nested row, column and HTML components. I have added a custom CSS FILE as well.

Now when I create a table component, it just keepd displaying ERROR_PROCESSING_COMPONENT. The table has just 8 rows, as it is a test table.

Also, I tested the same query and connection on new database, it shows the table as well as CCC chart. It works perfectly.

In my dashboard, I can display the CCC chart but the table just won't work. What could be the reason behind getting Error Processing Component.

Any Help/Experience will be appreciated.

Thank you.
