[ZEPPELIN-1217] Remove horizontal scrollbar in Zeppelin conf table

[AhyoungRyu]

What is this PR for?

This PR will fix ZEPPELIN-1217.

Current Zeppelin configuration table is hard to compare the env variable name with the descriptions at a glance because of the horizontal scrollbar. So I just removed the scrollbar.

@zjffdu Could you review this PR as a reporter?

@AhyoungRyu I follow the instruction here to build the doc https://github.com/apache/zeppelin/blob/master/docs/README.md#build-documentation, but fails. Here's the error after bundle install

Using bundler 1.12.5
An error occurred while installing RedCloth (4.2.9), and Bundler cannot continue.
Make sure that `gem install RedCloth -v '4.2.9'` succeeds before bundling.

I ran it on mac os 10.11, and also did xcode-select --install, do you know how can I fix this ? Thanks

[AhyoungRyu]

@zjffdu Did you run bundle install under ZEPPELIN_HOME/docs dir?

[zjffdu]

yes, I run it under ZEPPELIN_HOME/docs

[AhyoungRyu]

@zjffdu I'm not sure, your issue is related with this issue, but could you try

gem uninstall bundler
sudo gem install bundler

@zjffdu Yeah I also struggled with ruby and my OSX version issues. Anyway thanks for providing the link :)

[AhyoungRyu]

Is this good to go now?

[zjffdu]

LGTM 😄

LGTM, could be good to try changing that Table by something more descriptive.
Although the fact that there is 2 different configuration files with possible exclusive configurations doesn't help.

[AhyoungRyu]

@corneadoug I'm not sure I got your point correctly,
"You can configure Apache Zeppelin with both environment variables in conf/zeppelin-env.sh (conf\zeppelin-env.cmd for Windows) and Java properties in conf/zeppelin-site.xml. If both are defined, then the environment variables will take priority."

This short sentence is written in the above of the table. So do you mean this sentence is not enough? Or do you want me to add more description to the Description column?

[corneadoug]

@AhyoungRyu Just pointing out that using a Table component to show the config variable isn't great.

Merging if there is no more discussions
