   **Is your feature request related to a problem? Please describe.**
   A clear and concise description of what the problem is. Ex. I'm always 
frustrated when [...]
   Most of the columns showed in data panel have an icon to indicate their data 
types. 
   e.g. ABC - VARCHAR
   However, columns like FLOAT and DOUBLE PRECISION, also columns with NULL in 
some db are missing icons. 
   
   **Describe the solution you'd like**
   A clear and concise description of what you want to happen.
   Goal: to have a clear indication of what the data type of each column is
   improve the ability to infer datatype in data panel, 
   add icon for FLOAT and DOUBLE PRECISION, 
   set default icon, maybe ?  for unclear columns 
   
   The actual implementation might be complicated, but this is a necessary step 
for 1) drag and drop  2) dynamic control from a UX perspective
