Baseline Balance - T-Test - Missing Values

I want to create a balance table on STATA. It is a baseline dataset conducted as a part of an RCT. However, some of the variables have missing values. The number of missing values the variables have varies from 18 to 97. N is 2000, and the data is at the household level. How do I account for these missing values while running the t-test? What is the command I use on STATA?

Thanks!
