The legend inside the plot hides the panel.grid.
Is there a workaround?

Is it possible to adjust the thickness of the strata indicators?
The indicators in the legend are not as thick as in the risk.table.

How to adjust the fontsize of the risk.table?
I want the fontsize of the numbers at risk to be 20.
Not the title of the risk.table.

As the labels are quite long resulting in shifting the No at risk to the right.
Thus, they are not in line with the x-axis of the plot.
How to reposition the strata labels on top, above the number at risk? Is there any possibility?
