calcite建表语句解析时，需要进行的字符匹配序列

calcite建表语句解析时，需要进行的字符匹配序列：

varchar添加了长度之后就会报错，估计是没法匹配左括号吧，

 final public void TableElement(List<SqlNode> list) throws ParseException {
    final SqlIdentifier id;
    final SqlDataTypeSpec type;
    final boolean nullable;
    final SqlNode e;
    final SqlNode constraint;
    SqlIdentifier name = null;
    final SqlNodeList columnList;
    final Span s = Span.of();
    final ColumnStrategy strategy;
    if (jj_2_4(2)) {
      id = SimpleIdentifier();
