Vectorize arguments to row_spec to allow control of individual cell elements.

[warnes]

This resolves #773 by vectorizing the arguments to row_spec and sub-functions.

Example use from the update man page:

x <- head(mtcars)
k <- knitr::kable(x, "html")

# First two rows bold and italic
row_spec(k, 1:2, bold = TRUE, italic = TRUE)

# Color one header background red with white text
row_spec(k, 
         row = 0, 
         background=c("","red",rep("",9)),
         color=c("","white",rep("",9))
         )

# Color columns of header alternating grey and green, via recycling
row_spec(k, 0, color=c('grey','green'))

# Color columns alternating grey and green in all rows, via recycling
row_spec(k, 0:nrow(x), color=c('grey','green'))

# Same thing using `column_spec`:
k |>
column_spec(seq(1, ncol(x)+1, by=2), color='grey') |>
column_spec(seq(2, ncol(x)+1, by=2), color='green')

The conflicts are pretty easy to resolve, but I'm not sure how to add them to the PR. @haozhu233 should take a look and decide whether the changes are desirable.

[warnes]

@dmurdoch I merged in the changes from master and resolved the conflicts.

[dmurdoch]

I think something went wrong in the merge - the removal of spec_barplot (from mini_plots.R) was intentional, and it looks like your change restores it.

[haozhu233]

Sure, I think this feature aligns with what we have in column_spec (33b865f). @warnes If you get remove spec_barplot that would be great!

I will do a few more testings tonight.

[warnes]

I’ll fix that tomorrow.
