revealRow
Brings the row rowIndex names into view, and returns whether it was reached.
Revealing is a gesture rather than a declaration: it scrolls where it is called and leaves nothing behind, so no later pass scrolls back and where the user scrolls afterwards stands.
A row is revealed once the table holds it, which is what an effect keyed on the data runs after: the rows a click declares reach the table on the composition that click triggers.
false means nothing was revealed: no table is bound, the rows the table currently holds have no such row, or a row filter hides it, which leaves it nowhere to be shown. true means the table was asked to show it, which scrolls the pane the table is in; a table in no scroll pane has nowhere to scroll.
Return
whether the table shows that row and was scrolled to it.
Parameters
the row to bring into view, named the way selectedRowIndices names one - by its index into the table's rows, not the position it is drawn at.
