0x08 | UInt32 | Data offset. Points to the row data. |
0x0C | UInt32 | Row data size. Size of the data of each row. |

After the header comes all the columns. Each has the following structure:
Offset | Type | Description | |||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

Hash
A list of known hashes can be found here respectively here. The hash algorithm is demonstrated by the following C# code:
public static uint CalculateHash(string Name) { ushort Hash = 0; for (int i = 0; i < Name.Length; i++) { Hash *= 0x1F; Hash += Name[i]; } return Hash; }
Row
The rows consist of data. The data is specified by the columns. The string table comes after all row entries.
