Feature-Table Grid disappears when including

Question

Seems likely to be related to Solved: FeatureTable 4.30 failing to display grid - Esri Community

Using 4.33 with Map and Feature-Table components and very minimal custom CSS, the table's rows do not display... this can be resolved by removing the <!doctype HTML> and using "quirks", but this seems like a last resort; we'd much rather understanding the behavior than sidestep it.

Having recently dealt with this issue, it appears that the solution is to give your FeatureTable an id and specify its height in the CSS, otherwise the height will be 0px.

#table{
  height: 500px;
}
