R knitr - kable table html formatting for small text -

-

i trying format table in r markdown (compiling html) using knitr::kable small possible. perhaps making text smaller example. googling around lot have figured out how control these individual elements, table stays same size. thought should smaller elements required less space, did not happen.

so else have set make table smaller?

here code:

--- title: "kable table formating" output: html_document --- <style type="text/css"> <!--   td{     font-family: arial;      font-size: 4pt;     padding:0px;     cellpadding="0";     cellspacing="0"   }   th {     font-family: arial;      font-size: 4pt;     height: 20px;     font-weight: bold;     text-align: right;     background-color: #ccccff;   }   table {      border-spacing: 0px;     border-collapse: collapse;   } ---> </style>  ```{r echo=t} library(knitr,quietly=t)  n <- 14 m <- runif(n*n) dim(m) = c(n,n) df <- data.frame(m) kable(df,padding=0) ```

and here output - don't need whitespace:

you need add format="html" kable call , you'll have it. default, kable produces code markdown table (compare results of kable(df) , kable(df, format = "html")

```{r echo=t} library(knitr,quietly=t)  n <- 14 m <- runif(n*n) dim(m) = c(n,n) df <- data.frame(m) kable(df, format = "html", pad=0) ```

which looks this:

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
