Description

Environment

  • Package version(s): Table 4.7.7
  • Operating System: macOS Version 12.6.1
  • Browser name and version: Chrome Version 107.0.5304.110 (Official Build) (arm64)

Steps to reproduce

  1. Drag any column to reorder it to be the first column, but release the drag passed the first column position

Blueprint Documentation - drag passed first column breaks table.webm

Actual behavior

The table is stuck in column reorder mode and is no longer interactive.

Expected behavior

The select column becomes the first column, but more importantly, the table is still interactive.

Possible solution

If pointer-events: all; is removed from the invisible overlay (.bp4-table-reordering-cursor-overlay), the column does not move as expected, but the table remains interactive for the user.

Research direction
Investigate the drag reorder functionality in the Blueprint Table component. The issue occurs when a column is dragged past the first column position, causing the table to become non interactive. A possible solution is to remove `pointer events: all;` from the `.bp4 table reordering cursor overlay` CSS class, but further testing is needed to ensure columns still move correctly. Look at the relevant source files in the `@blueprintjs/table` package, particularly the reordering logic and overlay styles.
