When updating the layout, why do the columns in the DataTable collapse in Bokeh?

edit

The columns in the DataTable may collapse in Bokeh when updating the layout because the table may not have enough space to display all columns in their full width. This can happen when the size of the table is reduced or when new columns are added. To prevent this from happening, you can try increasing the width of the table or reducing the width of the columns. You can also consider using tools such as pagination or scrolling to manage the display of large data tables.
