I am using Apex version 5.1.4
I have an interactive grid that has a column of textarea, this column is for notes.
I resized the column based on the following Interactive Grid column widths – HardLikeSoftware and the following discussion. How to control interactive grid columns width?
The column could be resized and looks good when it is not being edited.

However, when I edit the column, the editable area is very small and does not extend to the size of the column. Is there a way to fix this so the editable area is as large as the column when the field is clicked?
