Graphics, Figures & Tables ⇒ Multiple Rows in Table Headers

[sw3quant]

hello.

my MWE is:

Code: Select all

\begin{center}
\captionof{table}{\bf CME GLOBEX Interest Rate Futures.}
\tiny
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|}
  \hline
  {\bf Name} & {\bf GLOBEX Ticker} & {\bf tickdata.com Ticker} & {\bf Bloomberg Ticker} & {\bf Daily Data Start Date} & {\bf Tick Size} & {\bf Tick Value  (\$)} &{\bf Contract Size (\$)} &{\bf Value/Point} &{\bf Quoting Spec.} & {\bf Int. Margin (\$)} & {\bf ADV (lots)} \\
  \hline \hline

  \hline
\end{tabular}
\label{irDataTable}

\normalsize

when I go to print this to PDF in A4 I see that its wider than the page due to long headers. Thus I wish to put the headers on two lines.

I have tried all the usual approaches (e.g. \parbox[c]{1.5cm}{tickdata.com Ticker}) but they all seem to skew the text off-center/ require to specify box size etc, which I am sure is incorrect.

What would a latex expert advise?

Thank you.

You could use p columns, instead of c, or just p headers. In general, for every formatting which you repeat, define a macro. So it's much easier to make changes. For example:

Code: Select all

\usepackage{array}
\newcommand{\head}[2]{\multicolumn{1}{>{\centering\arraybackslash}p{#1}}{\textbf{#2}}}

and in the table just write

Code: Select all

\head{1.5cm}{tickdata.com Ticker}

and similar for the other header entries.

\bf is an obsolete command, use \bfseries instead, or \textbf{...}. \normalsize is not necessary, since the effect of \tiny is limited by the center environment.

The table is hardly readable. I strongly recommend to use booktabs, and to remove vertical lines, I would use just horizontal lines in such tables.

I expect this table to be read row by row, not column by column. Or would you read the "Daily Data Start Date" column from up to down? Because the column is a vertical block, without horizontal lines. I would expect it the other way round. Vertical lines should not block the horizontal reading.

Before any adjustments the table comes out looking like the attached file.

This is how I meant it to be viewed with verticle lines seperating the columns. Here you see that the width of the headers in each col is much wider than the width of the data inside the col, hence I wanted to put the headers on more than one row.

I would rather keep things simple for the moment so dont want to implement macros. I have to share the latex with other authors who dont have time to learn about them. Could you be so kind as to explain your solution without macros?

You say "You could use p columns, instead of c, or just p headers." Are you suggesting replacing "c" in "\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|}" with "p" ?

thank you

[Stefan Kottwitz]

Macros are simple and effective. Just copy the two lines I gave into your document preamble. This already works, later you just write

Code: Select all

& ... \head{1.2cm}{GLOBEX Ticker} & \head{1.5cm}{tickdata.com Ticker} & ...

in your table. That is simple. Without macro, you would have to repeat such \multicolumn expressions for each header.

ok. added the macro. my code now reads:

Code: Select all

\normalsize

this gives the PDF image as attached.

I have two questions.

1. You see that the header row no longer has verticle lines at either end. How do I add them back?
2. Some of the text isnt central to the below data (eg see tick size col.)

many thanks for your help!!!

[Stefan Kottwitz]

You can insert the | for the vertical line in the macro as well, with p{#1}, so the macro definition becomes

Code: Select all

\newcommand{\head}[2]{\multicolumn{1}{>{\centering\arraybackslash}p{#1}|}{\textbf{#2}}}

This makes all "right" vertical lines. One left would be missing still, but it's easily fixed by starting with a normal header, such as:

Code: Select all

\textbf{Name} & \head{1.0cm}{GLOBEX Ticker} & ...

because the normal header already has all lines.

Regarding the centering: the text is centered within the p{Xcm} column, i.e. for the centering it's required to make this cell as wide as the whole column. This brings us back: so it's better to make all as p columns, as earlier said.

Changed macro, new column definition:

Code: Select all

\usepackage{array}
\newcommand{\head}[1]{\textbf{#1}}
\newcolumntype{C}[1]{>{\centering\arraybackslash}p{#1}}
...
    \begin{center}
    \captionof{table}{\bfseries CME GLOBEX Interest Rate Futures.}
    \scriptsize
    \begin{tabular}{|C{1.5cm}|C{1.2cm}|C{1cm}|C{1.8cm}|C{1.6cm}|C{1.3cm}|C{1.3cm}|C{1.1cm}|C{1cm}|C{1cm}|C{1.6cm}|C{1.2cm}|}
...
