Aligning Columns with knitr kable function

Question

I am performing a simple task: creating a table and outputting it using R Markdown to pdf as follows:

library(knitr)
kable(datatabl         


        

Answer 1

You can also use the length function to create a vector for all rows in a vector/dataframe without having to hard code a length. The example below left-aligns all the columns in the mtcars data frame no matter the length.

 kable(mtcars, align=rep('l', length(mtcars[,1])))
