I have imported the data into the UItable and i would like to have an indicator which is the lamb to switch to 'red' if there is any missing data like in the table. Is there any way i could do it? Thank you

You can do it in the following way:
  1. Add a buttonPushedCallback for the button 'Check for missing data'
  2. In the callback, check if there are any missing values in table using ismissing function
  3. Check if the logical array output of the ismissing function contain any 1's i.e missing values
  4. If 1's exist, change the color of lamp to 'red', else leave it in as is in green.

hi! thank you for the answer.
I have tried iterating the logical array (code shown below).However, my lamp continue turning out green which means that there are no missing datas when in fact, the data sample that i am using has 2 missing datas.
I am guessing that it continue to loop hence the error. Should there be a break after it found the first missing data
