# tableNum

An array of unsigned 8-bit integers that map modifier bit combinations to table numbers. These values are indexes into the keyToCharTableOffsets array in a UCKeyToCharTableIndexstructure; these, in turn, are offsets to the actual key-code-to character tables, which follow the UCKeyToCharTableIndex structure in the 'uchr' resource.

## Declaration

```swift
var tableNum: UInt8
```
