LL parser empty stack. The states and the transition function are not explicitly given; they are specified (generated) using a more convenient "parse table" instead. The table provides the following mapping: If the parser cannot perform a valid transition, the input is rejected (empty cells). 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
