I don't understand why you're iterating across the columns:

     for column in range(5):

and also setting multiple columns on each iteration:

     searchFrameObject.tableWidget.setItem(row,column,item)
     ...
     searchFrameObject.tableWidget.setItem(row,column+3,item)
     ...
     searchFrameObject.tableWidget.setItem(row,column+4,item)

That means that: when 'column' is 0 you're setting column 0 to
result.name, column 3 to result.stock, and column 4 to
result.minimum_bound; when 'column' is 1 you're setting column 1 to
result.name, column 4 to result.stock, and column 5 to
result.minimum_bound; etc.
