Styles do not read in correctly in certain circumstances about xltabr HOT 3 CLOSED

Because a list can be accessed by number or by index, this overwrites a style if value is a number

So for instance, if a cell anywhere has the number 3 in it, and the 3rd item in the list is title, then the title will be overwritten

from xltabr.

Note the underlying problem was essentialy this

> a <- list()
> a[[1]] <- 100
> a[["1"]] <- 20
> a
[[1]]
[1] 100

$`1`
[1] 20

> a <- list()
> a[["1"]] <- 20
> a[[1]] <- 100
> a
$`1`
[1] 100
