Currently the README examples rely on fictitious files like file.csv or table.vot. This makes it difficult to try out the examples. If example files were placed in a directory (for example examples), then it would be possible for the user to copy/paste all the examples and more quickly understand how to use the package.

Hi,
I found that the addTable does not keep the units from a Table (from astropy.table import Table).
So, there are no units in the Byte-by-byte Description of file, only ---, even if the Table has the each column with own unit.

Doing something like this:

data1 = np.random.normal(loc=0, scale=1, size=(1000,3))  
data1_names = ["col1", "col2", "col3"]  
data1_descriptions = ["Column 1", "Column 2", "Column 3"]  
data1_table = Table(data1, names=data1_names)  
for i, n in enumerate(data1_names):  
  col = data1_table[n]  
  col.description = data1_descriptions[i]  
  col.unit = "u{}".format(i+1)  
tablemaker = cdspyreadme.CDSTablesMaker()  
table1 = tablemaker.addTable(data1_table, "Table1.dat", description="This is the description of Table1.dat")  
tablemaker.writeCDSTables()  
tablemaker.makeReadMe()  

Produces this:

Hi! I had the following error during the execution of python3 setup.py install --user :

ValueError: bad marshal data (unknown type code)

It was solved by removing all *.pyc files included in the source code.

Expected behavior:
A column of floats has all decimal places persevered.

Actual behavior:
A column of floats is rounded to two digits and put into scientific notation (i.e. 0.951366 is displayed as 9.5e-2).

Steps to reproduce:
I follow the example on the readme and I've tried explicitly defining the format with set_format, but that seems to be ignored.
I'm using an astropy table with ~1.6 million rows, so it'd be difficult to share the actual data. Not all float columns have this behavior and it doesn't happen when I use a test set of only 100 rows--I see the actual behavior when I load the entire dataset.

Version: 1.3.0

 % pip install git+git://github.com/cds-astro/cds.pyreadme.git

fails due to a problem with installing the dependency "logging" from pypi.
Is this dependency needed? I though logging was included already in any recent version of python.

Hello,

Many thanks for this module!

I want to specify the formatting for the output columns in the output files - even though I have specified a format in an astropy Table object '{:5.2f}' for example - the tablemaker.makeReadMe() writes out either Float format or occasionally Scientific Exponential format - if you look at line 3 in the two ReadMe files below, you see one is F7.5 but the other is E5.1

How do I force makeReadMe() to write out a specific format?

I assume it is something I can set in a CDSColumn but I cannot work out what variable I need to set in the CDSColumn....

Hi, I have some astropy tables which I am converting into CDS tables for upload. Some of the physical quantities for my table entries are missing, and those array elements are filled with NaNs.

The writeCDSTables() runs without crashing, but replaces all NaN values with 0 (this is problematic).

The makeReadMe() crashes and returns: ValueError: cannot convert float NaN to integer, and hence does not generate an output.

Is there a way for NaN values to be supported?

Many thanks.
