Description

In Flink cdc connectors，it supports regex to match multi-tables，for example：

CREATE TABLE products
(
    db_name       STRING METADATA FROM 'database_name' VIRTUAL,
    table_name    STRING METADATA FROM 'table_name' VIRTUAL,
    operation_ts  TIMESTAMP_LTZ(3) METADATA FROM 'op_ts' VIRTUAL,
    operation     STRING METADATA FROM 'row_kind' VIRTUAL,
    order_id      INT,
    order_date    TIMESTAMP(0),
    customer_name STRING,
    price         DECIMAL(10, 5),
    product_id    INT,
    order_status  BOOLEAN,
    PRIMARY KEY (order_id) NOT ENFORCED
) WITH (
      'connector' = 'mysql-cdc',
      'hostname' = 'localhost',
      'port' = '3306',
      'username' = 'root',
      'password' = '123456',
      'database-name' = '(^(test).*|^(tpc).*|txc|.*[p$]|t{2})',
      'table-name' = '(t[5-8]|tt)'
      );

in doris-flink-connector，I tried using regular expressions, but failed，so How should I use it，thanks！
