Enum TableExpr 

pub enum TableExpr {
    Table {
        name: String,
        alias: Option<String>,
    },
    Derived {
        subquery: QueryExpr,
        alias: String,
        columns: Option<Vec<String>>,
    },
    Join {
        left: Box<TableExpr>,
        right: Box<TableExpr>,
        kind: JoinKind,
        constraint: JoinConstraint,
    },
}

SP33: one entry in the FROM clause — a base table, a derived table (subquery), or a join of two table-exprs. The comma form (FROM a, b) is a Vec<TableExpr> with len > 1 (implicit cross join).
