[Bug] knitr kable not work with caption with _ symbol in latex format

[borisalmonacid]

Work:
knitr::kable(head(mtcars, 1), format = "latex", caption = "First sample caption")

Not work:
knitr::kable(head(mtcars, 1), format = "latex", caption = "First sample caption _")
knitr::kable(head(mtcars, 1), format = "latex", caption = "First sample caption _5 ")
knitr::kable(head(mtcars, 1), format = "latex", caption = "First sample caption _ 5")

Saw this randomly. kable doesn't escape caption. You need to manually escape that knitr::kable(head(mtcars, 1), format = "latex", caption = "First sample caption \\_")

Thanks @haozhu233! I was just waiting for someone to type out the answer in my mind. 😁
