Deselect Cell From Range

[ailton-lopes]

Hello,

Describe the bug/suggestion
I would like to make a suggestion for improving the Selectable Cell Range functionality, including an option to check if the cell is already part of a range or disregard it if Ctrl + Mouse Click is pressed.

Tabulator Info

• 6.0.1

Examples:

• pressing ctrl + click on the same cell 5 times, the table.getRanges() function returns length=5 with the same targets (start/end). This also occurs if you press Ctrl + drag the mouse in the same range range. The same cells are considered in the ranges
• does not allow deselecting a cell/cells within a range by pressing Ctrl + Mouse Click

To Reproduce
https://tabulator.info/examples/6.1#range
1- select range from the 'Progress' column from line 2 to 5
2- press Ctrl + Mouse Click to deselect any cell in the range. Do not deselect.
3- Selects range from line 1 to line 5, from the Name column to the Rating column. Now press Ctrl + Mouse Click on row 2, from the Name column to the Rating column. It will not deselect. And if you use the table.getRanges() function, it will return 2 ranges
