15 Tips for Designing Terrific Tables

Tables of information are boring.

In a sense, they’re meant to be that way. A good table communicates a lot of information in a concise, easy to understand way. Because the emphasis really should be on the information, over-designing a table can kill the effectiveness. However, in the right hands, clever design can not only make a table more attractive, but can actually increase readability.
Today we’ll take a look at several ways you can improve the functionality and aesthetics of your tables. One of the most common places we currently find tables online is on a web app’s pricing page so most of our examples will take this form, just keep in mind that these principles can apply to any type of informative grid (whether or not it’s actually a <table>).

Vertical, Horizontal or Matrix?

As always, we’ll start with the obvious. The first step is deciding on a general structure of your table. The structure you should choose depends on the type and complexity of the information you’re presenting. Choosing between vertical columns and horizontal rows can largely depend on personal preference. Sketch out your content in each form and decide which method you think conveys the information best. Obviously, if your message is based on multiple variables, a matrix is the way to go. Here’s a quick example of each to get you started.

Vertical

Horizontal

Matrix

Start in Excel

For the record, this is the first, and hopefully the last, time you’ll here me suggest using Microsoft Office for anything design related. The truth is, tables are undoubtedly easy to make in Excel; that’s pretty much what it does. Compare this with the time it takes you to hard code the organizational structure in HTML and Excel will win every time.
Today I stumbled across a great little web application called Tableizer that allows you to paste in your tables from Excel to magically transform them into HTML. You’ll still have to handle most of the styling on your own but you’ll definitely save some time on the front end.

Use a Table Generator

Hate Excel? Don’t feel bad, me too. If you’re still looking to save yourself some time on creating the basic skeleton of an HTML table, there are tons of online generators that will get the job done. Note that I said “basic skeleton,” don’t go thinking you’re done after using one of these to cheat your way out of a little coding. You’ve still got a long way to go if you don’t want it to suck.
Here’s a quick list of free table generators to save you a Google search:

• Table Generator
• Kotatsu
• Spectrum Research

A Little Styling Goes a Long Way

Now that you’ve got a basic table, the first step towards taking it out of the 90′s is to add some CSS. Of course, you can go crazy and spend hours experimenting with different styling options, just remember that even a little bit of color and font styling can drastically improve both the readability and attractiveness of the table.
Here are a few tutorials on how to properly style a table.

Add a Featured Section

This is extremely common in pricing tables, but is applicable to any table. Think about the information in the table and consider whether you want the viewer to focus on a specific portion. Whether it’s the plan with the best value or a popular element in a list of features, try varying the color and/or size to make it stand out from the rest.
There are definitely plenty of ways, both subtle and over the top, to make the featured section stand out. Here are a few for inspiration:

Make the Information Sortable

If you’re creating tables with a lot of information organized into several columns, it’s a good idea to consider adding a sort feature so your users can choose the way they want to see the information organized. Mint.com integrates table sorting into your list of transactions, making it super easy to change from a date-based view to a category-based view so you can identify areas where you tend to spend a lot of money. As you can see in the screenshot above, I tend to enjoy eating greasy fast food a lot more than I should!
Here are a couple of table sorting tutorials using different methods:

• Sort Table Rows Using Ajax (WoorkUp)
• Table Sorting JavaScript (Yoast)

Use Icons

As I said above, the point of organizing information into tables is to make it understandable at a glance. By cutting down the necessary reading, well-designed icons can drastically improve the speed at which a visitor can comprehend the information in your table.
Beware, this goes both ways. Sloppy icons can leave your users scratching their heads trying to figure out what you’re trying to communicate.

Add Zebra Stripes

This is a pretty basic idea dating back to as long as tables of information have existed. Adding alternating row colors helps your eyes follow the line of communication and connect the floating information in the center of a table with the anchored category on the side or bottom. This simple technique can increase the readability of both large and small tables, but it’s a good rule of thumb to always include stripes (or some other visual aid) if your table requires the reader to connect pieces of information that are more than an inch or two apart.
Here are some free resources for adding stripes to your tables:

• MooTools Zebra Table Plugin (David Walsh)
• PHP Zebra Striping a Table (CSS-Tricks)
• jQuery Zebra Stripe a Table (CSS-Tricks)

Crank Up the Web 2.0

Shiny web 2.0 style design might be a bit overused, but it can still be a great attention grabber. I definitely don’t recommend adding too much superfluous visual flare to a large table that is already fairly complex. In these instances, simple is probably the way to go. However, if you’re creating a fairly small table with only a few items, there’s no harm in making it look amazing.

Go Minimal

Hate that shiny web 2.0 look from the previous tip? No problem, there’s an even stronger argument for minimizing the table graphics. This allows the user to focus on the content without any unnecessary distractions. Use clean, subtle grid lines (or no lines), simple fonts and colors that contrast nicely with your background.

Add a Search Feature

Sometimes adding a sort feature just isn’t enough. When you’ve got pages of information to sort through, nothing beats a search field.

Don’t Overload the Table with Redundancies

App developers love to tout huge lists of features and a table is definitely a natural and even appropriate way to go about it. However, sometimes designers pack tables with a lot of unnecessary, redundant information that could be presented in a much better way.
Check out the example above from Invoice Machine. The four plans they offer are nearly identical with the exception of three features. This makes for 15 unnecessary rows that leave your eyes jumping back and forth to connect the check marks with the corresponding feature. A simple bulleted list or chart that said “All of our plans include the following features:” would allow users to quickly see that no matter which plan they choose, they get all of these features. Then the table could be reserved for areas of differentiation, which would cut it down to a much more manageable 3 or 4 rows. Again, let me stress that tables should make the information more readable. If your table isn’t meeting this goal then it’s counter-productive.

Create Expandable Areas

Another great feature that you can add to your tables is the ability to expand certain rows. This allows you to place a lot of content into a relatively uncluttered space. Pulling this off is pretty simple with a jQuery plugin called jExpand. Here’s a tutorial from jankoatwarpspeed on how to implement it.
If you’re using an expandable table, just be sure that your headings make it completely clear where to find certain information. The last thing you want is annoyed users, sifting through each section to find what they want.

Highlight Relationships

This is a technique that really increases the readability of a complex table or matrix. The idea is to highlight whatever cell the user is hovering over along with both the column and row that it belongs to. Check out a live example here.

Add a Dynamic Selection Effect

Here’s another tutorial from “Ask The CSS Guy” on how to add a feature that allows the user to select a given column in a table (say a pricing plan), which then highlights and expands to show more information. It’s the same concept as the expanding jQuery example above but with a very different intention and overall effect. Check out the demo here and the full tutorial below.
