PF4 Table: Cannot read property 'title' of null

[dlabrecq]

It appears that the table generates a Cannot read property 'title' of null error if any cells are null or undefined.

Appears to be generated from this line of Body.js?

@karelhala This may interest you? My work around was to ensure item.label is not null. Not sure how this is related to the property 'title', but was quite difficult to debug.

rows.push({
  cells: [
    item.label ? item.label : '', <<<<
    this.getMonthOverMonthCost(item, index),
    this.getTotalCost(item, index),
  ],
...

Thanks for bringing this is up yes, it is the same as trying to render null or undefined in React. However we should add warning message or something to notify consumer that they shouldn't send null/undefined to cell.

Sounds good. Perhaps we could add a check to the title: curr.title || curr, line in Body.js?

Can we go ahead and close this one out?

I believe @karelhala suggested adding a warning message? Would be better than throwing an exception.
