vis_dat() can't handle new tibble name repair conventions
There are new name repair conventions as of tibble 2.0.0 that are exposed in other packages (e.g., readxl). It renames blank column names ("") to the form of ..1, ..2, etc: https://tibble.tidyverse.org/reference/name-repair.html
Unfortunately it looks like vis_dat() can't handle this kind of column name 😭

x <- tibble(`..1` = 1)
x
#> # A tibble: 1 x 1
#> ..1
#> <dbl>
#> 1 1
vis_dat(x)
#> Error in .f(.x[[i]], ...): ..1 used in an incorrect context, no ... to look in

I dug into vis_dat() a bit and the issue is within vis_gather_(), specifically with tidyr::gather_(). gather_() is deprecated so that would probably be why it doesn't support this new naming convention. Just wanted to flag it to you!
Edit: I actually don't really know if this is a "you" problem or a tidyr problem (e.g. can gather(), the "regular" function, handle .. names at all?)
Thanks for posting this issue, Sharla!
Indeed, even after the new release of tibble this still breaks with names that have two dots, e.g., (..1) - demonstration building from your lovely reprex:
library(tidyr)
library(tibble)
x <- tibble(`..1` = 1,
`..2` = 2,
x3 = 3)
# Gathering without specific reference works
x %>%
gather(key = "col_name",
value = "value")
#> # A tibble: 3 x 2
#> col_name value
#> <chr> <dbl>
#> 1 ..1 1
#> 2 ..2 2
#> 3 x3 3
library(visdat)
one_dot <- tibble(`.1` = 1)
two_dot <- tibble(`..1` = 1)
three_dot <- tibble(`...1` = 1)
vis_dat(one_dot)
vis_dat(three_dot)
vis_dat(two_dot)
#> Error in .f(.x[[i]], ...): ..1 used in an incorrect context, no ... to look in

I'll have a look at updating gather_ and have this fixed for the next release.
Thanks again for digging into this, I really appreciate it! :)
I think that it may not work because.. names are not syntactic -- seems like they are a regretful introduction by the tidyverse team that has now been fixed! There's lots of good tidbits in this chapter if you haven't seen it: https://principles.tidyverse.org/names-attribute.html 2.3 on especially
so i'm not sure if gather_ can even be fixed to allow them (but the introduction of them, which was happening via tibble, shouldn't happen anymore)
I think this is now resolved, as you said, @sharlagelfand - the .. names aren't syntactic anymore, so I think it's all good from here :)
