Exactly. Normally you use second-level tables for the long codes. In the first table, if code doesn't reach a leaf, tbl[code] holds a pointer to the next table to use.

For example, here's JPEG XL's Huffman decoder: https://github.com/libjxl/libjxl/blob/1c67f4eff0464e6241f365.... The branch uses a second table if the code was too long.
