问题 I may be blind, but this is a little different than the normal export-to-excel. I've created a solution and would like to know if this is the best way. Or even if there is another way to do it. Background: WinForms, VisualBasic, VS2012, N-Tier (backend is DB2). My DTOs are set up in order of the DB2 tables. My users want to see the fields in a certain order within the DGV AND be able to export the fields in the same order. Users can also rearrange and hide columns. Hidden columns should not

问题 The problem my application is trying to solve is this: Currently, several stored procedures are run, the data is manually copied out of the SQL results into a blank spreadsheet, and reporting analysts format the data.

问题 What I miss about Pandas(Python) working on R is the way a DataFrame is exported to excel. In R, ftable shows tables similar as pandas multiindex DataFrame. When I use to_excel in pandas every row and column is ok in every cell even merge cells in column names if necesary. In R I tried write.ftable with write.table df = data.frame(a = c(1:6), b = rep(c('G1','G2'),3), c = rep(c('A','D','F'),2), d = c('F','F','F','F','M','M')) df2 = ftable(xtabs(a~b+c+d, df), row.vars = 1) write.table(write
