    <p>This seems like it should be a piece of cake, but I haven't found the answer in Mathematica's documentation. Say I have two separate lists, for example x={1,2,3,4,5} and y={1,4,9,16,25}. I want to format these lists as a table with each list as a column, like this: </p> <pre><code>x y 1 1 2 4 3 9 4 16 5 25 </code></pre> <p>But if I do TableForm[x,y], I get only the first column, like this: </p> <pre><code>1 2 3 4 5 </code></pre> <p>If I do Grid[{x,y}], I get a table, but formatted as rows instead of columns, like this: </p> <pre><code>1 2 3 4 5 1 4 9 16 25 </code></pre> <p>Now, if I have my values as {x,y} pairs, rather than separate lists, then I can get <em>almost</em> what I want,like so:</p> <pre><code>Input: Table[{n,n^2},{n,1,5}]//TableForm Output: 1 1 2 4 3 9 4 16 5 25 </code></pre> <p>I say <em>almost</em>, because I'd like to have the variable names at the top of each column, and I'd like the columns justified so that the ones digits are always placed vertically in the "ones place", the tens digits in the "tens place", etc.</p> <p>So, back to my question: If I have two separate lists of the same length, how can I format them as a table of columns? I checked the MMA documentation for Grid and TableForm, but I couldn't find a way to do it. Did I miss something? If there's no direct way to do it, is there a way to transform two separate lists into pairs of values that could then be formatted in columns using TableForm?</p> <p>Thanks for any suggestions you might have.</p>

    3. CO@belisarius Some how I missed your last comment until just now. I've have (belatedely!) selected a "best" answer. Nevertheless, I encourage readers of this question who are learning Mathematica to take a look at some of the other answers, as each will add something to your understanding of how Grid and Tableform work.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
