Patternfly-react: Expandable doesn't match cellFormatters signature

[crackcomm]

Code from Compact expandable table does not work in patternfly-react-seed with "@patternfly/react-table": "^2.13.43".

thanks! i can try to address this in #1950. Still working on that now.

i've updated the PR for #1950 over in #2360. Will try to confirm it fixes this before merge. FWIW, the types for ICell are currently the following there... and cellFormatters is included.

export interface ICell {
  title?: string;
  transforms?: ((value: any) => IDecorator)[];
  cellTransforms?: ((value: any) => IDecorator)[];
  columnTransforms?: ((value: any) => IDecorator)[];
  formatters?: ((value: any) => IDecorator)[];
  cellFormatters?: ((value: any) => IDecorator)[];
  props?: any;
  data?: any;
  header?: any;
  cell?: any;
}

i've pushed a workaround for this issue for now and have changed the interface above to accept any types for now:
https://github.com/patternfly/patternfly-react/pull/2360/commits/4acf7c8c1ecc8920ba7707091d3953789cf7a16a

IDecorator is not accurate. This should really be more like:

cellFormatters: ((label: IFormatterValueType, { rowIndex, columnIndex, rowData, column, property }: IExtra) => formatterValueType) [];

The current problem w/ this is we have several different names for the formatter and transformer arguments like value and label, width, id, data etc:

export const collapsible = (value: IFormatterValueType, { rowIndex, columnIndex, rowData, column, property }: IExtra) => {

export const cellWidth = (width: number | string) => () => ({

export const sortable = (label: IFormatterValueType, { columnIndex, column, property }: IExtra) => {

export const headerCol = (id: string = 'simple-node') => {

const defaultTitle = (data: IFormatterValueType) =>

It would be nice to shore these up and type them all, but I feel this can be expanded upon in the future and any is the safest solution for now here...We will need more comprehensive test coverage to ensure this safely.
