Why is the column and width of a table in python creating an error

I'm creating a simple four column, one row table. However, when the code executes I receive the following error

Table 4 rows X 1 cols> with cell (0,0) containing 'D' data error - 1 columns in data but 4 in column widths".

The code is as follows:

colwidths = (46, 76, 48, 40)  
rowheights = (20)  
tabledata = ('DATE ', '3-20-2016', 'FIELD # ', '1')  
t = Table((tabledata), (colwidths), (rowheights))

I encountered a similar problem this week so i will put my solution here for others.

It seems there are two main causes:

  1. Your queryset may not be producing any iterable values - kindly check.

OR

  1. If you have several tables in a page, then one of your tables is not formatted well e.g. you have a <tr> ...<tr> instead of <tr> ...</tr>. note the closing /

My approach to this problem is to split the whole page into partials (with each table as a partial) and load them in the browser one by one.

You are likely to identify the table causing the error.

You simply need to wrap tabledata in another iterable to ensure its interpreted as all 5 items being on a single row, instead of 5 rows containing a single item? i.e. 

tabledata = [('DATE ', '3-20-2016', 'FIELD # ', '1')]
