latab 1.0.0

Tool to easily convert numpy arrays into latex tables with astropy units support.

LaTab

Utility to help convert numpy arrays to a LateX table. The main goal is to provide a code snippet with proper number and unit formatting, with a basic table layout. Formatting of the table itself is expected to be done manually by the user in the LateX document, but simpler features might be added in later versions if the need arises.

Examples

Imports and sample data

import numpy as np
from astropy import units
from latab import Table, FloatFormatter, FixError, AbsoluteError, RelativeError

array1 = np.array([13.35000606, 0.76642346, 1.42476496, 9.27577478, 3.83978828, 1.88922311])
array2 = np.array([1.8131508, 5.3586463, 5.6288616, 7.4245393, 8.1266426, 4.5811065]) * units.g / units.cm**3
array3 = np.array([9.47738782e+20, 9.06469621e+20, 2.50771562e+20, 8.85737743e+20, 7.04538193e+20,
                   8.90478371e+20]) * units.kg
errors = np.array([0.034574, 0.072827, 0.04782, 0.098236, 0.018896, 0.071311]) * units.g / units.cm**3
planets = ["Kepler137b", "Kepler137c", "Kepler137d", "Kepler137e", "Kepler137f", "Kepler137g"]

Example

(Table("Nobody expects the Spanish inquisition.")
 .serialColumn("Planet", 6)
 .dataColumn("Semi-major Axis [AU]", array1, FixError(0.0005))
 .dataColumn("$\\varrho$", array2, AbsoluteError(errors), FloatFormatter(2, 2))
 .dataColumn("Mass", array3, RelativeError(0.05))).print()

\begin{table}
    \centering
    \begin{tabular}{|c|c|c|c|} \hline
        Planet & Semi-major Axis [AU] & $\varrho$ [$\mathrm{g/cm^{3}}$] & Mass [$\mathrm{kg}$] \\ \hline
        1. & $13.350 \pm 0.0005$  & $1.81 \pm 0.03$  & $(9.477 \pm 0.4739)\cdot 10^{20}$  \\ \hline
        2. & $0.766 \pm 0.0005$  & $5.36 \pm 0.07$  & $(9.065 \pm 0.4532)\cdot 10^{20}$  \\ \hline
        3. & $1.425 \pm 0.0005$  & $5.63 \pm 0.05$  & $(2.508 \pm 0.1254)\cdot 10^{20}$  \\ \hline
        4. & $9.276 \pm 0.0005$  & $7.42 \pm 0.10$  & $(8.857 \pm 0.4429)\cdot 10^{20}$  \\ \hline
        5. & $3.840 \pm 0.0005$  & $8.13 \pm 0.02$  & $(7.045 \pm 0.3523)\cdot 10^{20}$  \\ \hline
        6. & $1.889 \pm 0.0005$  & $4.58 \pm 0.07$  & $(8.905 \pm 0.4452)\cdot 10^{20}$  \\ \hline
