This PR converts the change's `from` field from a list of tablePositions into a list of selected indices of rows.
It includes two tests for TableView and one for TreeTableView (the second test wasn't included due to an [issue|https://bugs.openjdk.java.net/browse/JDK-8232825] with key navigation), that pass with this PR and fail without it. ------------- Commit messages: - Convert change from list of tablePosition to list of rows Changes: https://git.openjdk.java.net/jfx/pull/710/files Webrev: https://webrevs.openjdk.java.net/?repo=jfx&pr=710&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8273339 Stats: 147 lines in 3 files changed: 143 ins; 0 del; 4 mod Patch: https://git.openjdk.java.net/jfx/pull/710.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/710/head:pull/710 PR: https://git.openjdk.java.net/jfx/pull/710
