Hi, I am having a go at the uni-table package (hi @dominik.pantucek! 🙂 ). This styling: ```scheme (uni-table->string tbl #:table-border '(solid light) #:col-borders '((solid left heavy)) #:row-borders '((heavy solid)(light solid)) #:row-style '((#:bg DarkGrey)()...)) ``` results in the picture below. 1. Notice that the last column has a "light" border on the right. I'd like to have the last column have both left and right borders "heavy". How can I do that? 2. I'd like my default style to alternate 2 colors on rows (grey, white, grey, white ...) to improve readability. But I don't know how many rows there will be in advance. Is there already a way to do that or should I cook up something of my own? 3. As I understand it from the docs, there currently is no facility to style individual cells, right? I have a strong interest in this package, so if life doesn't get in the way too much I'll definitely attempt to contribute! Thanks for the good work! ![table](https://global.discourse-cdn.com/free1/uploads/racket/original/1X/0b198c8ff24a73631e5cabaa726f8a3a01fa645d.png) ---

If you have the table, you ought to be able to compute a row-style (which is, after all, just quoted data) that has what you want based on the number of rows. ---

> If you have the table, you ought to be able to compute a row-style (which is, after all, just quoted data) that has what you want based on the number of rows. Thanks, I certainly can. I just asked because since Uni-table is a very new package, and I know Dominik is very prolific so perhaps some functionalities were not documented yet. ---

Is there already a way to do that or should I cook up something of my own? If you know the number of rows, it is really easy. ```racket #lang racket (require uni-table) (define tbl `((sepal_width sepal_length petal_width petal_length species) ,@(for/list ((i (in-range 10))) '(5.1 3.5 1.4 0.2 Iris-setosa)))) (print-uni-table tbl #:table-border '(solid light) #:col-borders '((solid left heavy right heavy)) #:row-borders '((heavy solid)(light solid)) #:row-style `((#:bg DarkGrey) ,@(for/list ((i (length tbl))) (if (odd? i) '(#:bg red) '(#:bg blue))))) ``` ![Screenshot from 2022-03-28 10-20-58](https://global.discourse-cdn.com/free1/uploads/racket/original/1X/4f1c88a704a031776bf3fb203a2ba10cd91238c5.png) Btw, support for lazy and/or splicing styles is planned. If I only wasn't too busy it would already be implemented (alongside support for really large tables). ---

> [@rscho](#): > > As I understand it from the docs, there currently is no facility to style individual cells, right? As you mentioned, it is a work in progress, however this is already there: ```racket (define tbl2 `((sepal_width sepal_length petal_width petal_length species) ,@(for/list ((i (in-range 10))) (for/list ((j (in-naturals)) (v '(5.1 3.5 1.4 0.2 Iris-setosa))) (uni-cell v #:style (if (odd? (+ i j)) '(#:bg cyan) '(#:bg green))))))) (print-uni-table tbl2 #:table-border '(solid light) #:col-borders '((solid left heavy right heavy)) #:row-borders '((heavy solid)(light solid)) #:row-style `((#:bg DarkGrey) ,@(for/list ((i (length tbl))) (if (odd? i) '(#:bg red) '(#:bg blue))))) ``` ![Screenshot from 2022-03-28 10-24-04](https://global.discourse-cdn.com/free1/uploads/racket/original/1X/c62368ad1ff22c63ccb3590f4b8204d43224e407.png) A bit extreme example, but you should get the point (see how the cell style overrides the row style as expected). ---

Thanks so much for your very informative answers (and for the package, which looks like it's going to turn awesome)!
