`etable()` drops whitespaces from factor labels

[etiennebacher]

When the factor labels contain spaces, those are removed by etable(). Is it possible to preserve them?

library(fixest)
packageVersion("fixest")
#> [1] '0.13.2'

test <- data.frame(
  y = 1:5,
  fac = factor(c("first cat", "second cat", "first cat", "second cat", "first cat"))
)

res <- feols(y ~ fac, data = test)
etable(res)
#>                              res
#> Dependent Var.:                y
#>                                 
#> Constant          3.000. (1.054)
#> facsecondcat    8.88e-16 (1.667) # <<<<<<<<<<<<<<<< "facsecondcat" instead of "fac second cat"

res <- feols(y ~ i(fac, ref = "first cat"), data = test)
etable(res)
#>                              res

Thanks again for this awesome package!
