List all machine states
List all tape symbols, including blank
Create one row for each current state
Create one column for each tape symbol
For each state-symbol pair, define the action
Write the next state
Write the symbol to be written on the tape
Write the head movement direction: L, R, or S
Use the format: current state, read symbol -> write symbol, move, next state
Fill every possible state-symbol entry
Add a reject or trap state if needed
Ensure the table is deterministic if required
Verify that every transition leads to a valid state and symbol action
