+## Use it with sparkline
+Well, this is not a feature but rather a documentation of how to use the `sparkline` package together with this package. The easiest way is sort of a hack. You can call `sparkline::sparkline(0)` somewhere on your document where no one would mind so its dependencies could be loaded without any hurdles. Then you use `sparkline::spk_chr()` to generate the text. Here is another example: [Chinese names in US babynames](https://cranky-chandrasekhar-cfefcd.netlify.app/)
+
+```{r}
+library(sparkline)
+sparkline(0)
+```
+
+```{r}
+spk_dt <- data.frame(
+  var = c("mpg", "wt"),
+  sparkline = c(spk_chr(mtcars$mpg), spk_chr(mtcars$wt))
+)
+
+kbl(spk_dt, escape = F) %>%
+  kable_paper(full_width = F)
+```
+
+
+
 # From other packages
 Since the structure of `kable` is relatively simple, it shouldn't be too difficult to convert HTML or LaTeX tables generated by other packages to a `kable` object and then use `kableExtra` to modify the outputs. If you are a package author, feel free to reach out to me and we can collaborate.

+* For line charts, x values can also be specified:
+*   <p>Sparkline: <span class="sparkline">1:1,2.7:4,3.4:6,5:6,6:8,8.7:5,9:3,10:5</span></p>
+*    $('#sparkline1').sparkline([ [1,1], [2.7,4], [3.4,6], [5,6], [6,8], [8.7,5], [9,3], [10,5] ])
+*
+* By default, options should be passed in as the second argument to the sparkline function:
+*   $('.sparkline').sparkline([1,2,3,4], {type: 'bar'})
+*
+* Options can also be set by passing them on the tag itself.  This feature is disabled by default though
+* as there's a slight performance overhead:
+*   $('.sparkline').sparkline([1,2,3,4], {enableTagOptions: true})
+*   <p>Sparkline: <span class="sparkline" sparkType="bar" sparkBarColor="red">loading</span></p>
+* Prefix all options supplied as tag attribute with "spark" (configurable by setting tagOptionsPrefix)
+*

+<h2>Use it with sparkline</h2>
+<p>Well, this is not a feature but rather a documentation of how to use the <code>sparkline</code> package together with this package. The easiest way is sort of a hack. You can call <code>sparkline::sparkline(0)</code> somewhere on your document where no one would mind so its dependencies could be loaded without any hurdles. Then you use <code>sparkline::spk_chr()</code> to generate the text. Here is another example: <a href="https://cranky-chandrasekhar-cfefcd.netlify.app/">Chinese names in US babynames</a></p>
