@strahe Make sure to get screenshots of this table. Especially the right most part. Since we are replacing a column, I don't think render should be affected but I would like to be sure. Also, this change will break terminateSectors method as the input for that method will change. You need do the following:

1. Update the index.html to use the updated column name "MinerAddress" as part of terminate & delete
2. Update terminateSectors to set address string as input and handle from there

Terminate works correctly.
