Dynamic Tables

An advantage of Pandoc pipe tables is that they can easily be combined with inline code to produce dynamic tables. Here is an example generating a table showing average gallons per 100 miles for foreign and domestic cars before and after adjustment for weight. We use a strict code block to te able to hide the commands and quietly to supress output, and then display the stored results in a pipe table.This is the input:

% A Dynamic Table

```s/
    quietly sysuse auto, clear
    quietly gen gphm = 100/mpg
    quietly regress gphm foreign
    mat b = e(b)
    quietly sum weight
    scalar mw = r(mean)
    quietly reg gphm weight foreign
    scalar dom = _b[_cons] + _b[weight] * mw
    local f %6.2f
```

The table below shows average fuel efficiency in gallons per 100 miles 
for foreign and domestic cars before and after adjustment for weight:


| Car Type   | Unadjusted            | Adjusted                  |
|:-----------|----------------------:|--------------------------:|
| Foreign    | `s `f' b[1,1]+b[1,2]` | `s `f' dom + _b[foreign]` |
| Domestic   | `s `f' b[1,2]`        | `s `f' dom`               |

Foreign cars use less fuel than domestic cars but are also lighter,
when we compare cars with the same weight the imports use 
six-tenths of a gallon more per 100 miles than the domestic cars.

And this is how this is rendered by the command markstat using dynatab.

As usual, you can reproduce this example by typing

markstat using dynatab

You need to download the script first because markstat works with local files.
