Is there a way to alternate row colors in a table?

[barbarat]

Sometimes it's hard to read a lot of data in a table. Is there a way to alternate the row color to something like default white and a really light grey?

[Aleš Laňar]

For that the best way could be apply CSS to global. Insert this:

table.confluenceTable td.confluenceTd.highlight-grey {
	background-color: #909090;
}

we have created our own UI plugin, which basically overwrites some of the default CSS.

cheap but powerfull. Might work for you too.

Here's how...UPVOTE to get more traction on this feature request:

Select columns or rows in a table to apply formatting

You can use the Table Plus Macro. See Styling Table Rows.

I realize this would work, but it feels wrong to me that the creator or the commercial product would be blatantly advertising it.

[Bob Swift]

I disagree, I think most people on this forum appreciate ideas for solving their problems with whatever is available (built-in, free, or commercial) and they can choose to ignore commercial solutions if they want. More-over a lot of people who already own the add-on find out about features they may not be aware of.

Unfortunately, confluence cloud doesn't allow you to set custom CSS.  But, if you want to at least see it in your browser, you could run the following command in your javascript console:

$("tr:nth-child(even)").css({"background": "rgb(250,250,250)"});

[Stephen Deutsch]

Actually, Confluence Cloud now sort of lets you set CSS globally.  If you change the Global/Space Look and Feel, you can insert the following in the header/footer:

{css}.confluenceTable tr:nth-child(2n+3) {background: rgb(250,250,250)}{css}

This will also work in Confluence Server if you have the Content Formatting Macros installed.
