reportlab

问题 I'm using ReportLab to write tables in PDF documents and am very pleased with the results (despite not having a total grasp on flowables just yet). However, I have not been able to figure out how to make a table that spans a page break have its column headings repeated. The code below creates a test.pdf in C:\Temp that has a heading row followed by 99 rows of data. The heading row looks great on the first page but I would like that to repeat at the top of the second and third pages. I'm keen

问题 I'm referring this link for generation of Pie Chart. In this the colors are pre-defined for each data, ie 10 colors for 10 data points. What if I have 11 data points and then there will be no color for that 11th data point. I want something dynamic which should automatically pick a color by itself and plot it on the pie. I found this link and this link, but the colors over here are not catchy and not at all good. Can someone please brief me about how to get catchy colors in pie graph? Thanks
