To make the table more compact, only the non-terminal rows are commonly displayed, since the action is the same for terminals. To explain an LL(1) parser's workings we will consider the following small LL(1) grammar: and parse the following input: We construct a parsing table for this grammar by expanding all the terminals by column and all
