mattcasters opened a new pull request, #7527:
URL: https://github.com/apache/hop/pull/7527

   ## What changes were proposed in this pull request?
   
   Adds a **Navigate to column** action on the shared `TableView` toolbar (and 
context menu). Clicking it opens an `EnterSelectionDialog` with a search bar so 
you can pick a column by name; the table then scrolls horizontally to make that 
column visible.
   
   This helps when working with wide grids (data preview, field mapping 
dialogs, etc.) where finding a column by hand is tedious.
   
   Closes #6852
   
   ## What was tested?
   
   Manually verified in Hop GUI:
   
   - Toolbar button appears next to the filter control on `TableView` instances
   - Searchable column list dialog opens and filters column names
   - Selecting a column scrolls the table so that column is visible
   - Context menu entry works the same way
   - Cancel leaves the scroll position unchanged
   
   ## How to test?
   
   1. Open a pipeline with a transform that has many fields, or preview data 
with many columns
   2. In the `TableView` toolbar, click the new **Navigate to column** (search) 
button
   3. Filter/select a column that is off-screen to the right
   4. Confirm the grid scrolls so the column is visible
   5. Repeat from the table context menu
