Update data viewer column resizing

[renkun-ken]

What problem did you solve?

Closes #1120

suppressColumnVirtualisation: true does not look like a good idea mainly for performance reasons. Setting minWidth and width seems to be enough for most purposes.

(If you do not have screenshot) How can I check this pull request?

n <- 1000
df <- data.frame(id = 1:n)
for (i in 1:100) {
  df[[paste0("abcdef", i)]] <- rnorm(n)
}

View(df)

LGTM, thanks! Works as expected on Arch
