sub-group analysis adjusted for other covariates

[ayueme]

Hello there,
Sub-group analysis adjusted for other covariates is widely used in papers. For example, the figure 3 in this paper.

The TableSubgroupxxx functions can only have one covariate. Just like the following:

# OK
TableSubgroupMultiCox(
  formula = Surv(time, status) ~ rx, # only 1 covariates is supported
  var_subgroups = c("sex","age","obstruct","perfor","adhere"), 
  data = df)

# NOT OK
TableSubgroupMultiCox(
  formula = Surv(time, status) ~ rx + bmi + smoke, # this not work
  var_subgroups = c("sex","age","obstruct","perfor","adhere"), 
  data = df)

So would you mind adding this feature?
Thank you very much.
