Hello, I found this a very useful tool, but can you support Chinese, because if the table content is Chinese and the table cannot be aligned, I try to modify the realLength function in content.go and change utf8.RuneCountInString to len, but it no effect

Fix #6.

For CJK characters, when displayed in terminal, they take more that one position. For whatever reason, what is returned by utf8.RuneCountInString is not expected.

this patch uses https://github.com/mattn/go-runewidth to get the correct content length of the cell. see https://play.golang.org/p/2xDzwKjK7H8

Thanks for the package!

Might be nice to strip ansi escape sequences with something like this hack, so that the cells are still calculated properly allowing colors etc.

Simple but powerful wheels. The only regret is that there is always a divider line between header(footer) and body even with customized style.

This PR fix the problem and add a predefined style called CompactClassic which do not have separator line between header and body. Inspired by kubectl

table := st.New()
table.Header = &st.Header{
    Cells: []*st.Cell{
        {Text: "UUID", Align: st.AlignLeft},
        {Text: "NAME", Align: st.AlignLeft},
        ...
    },
}

table.Body.Cells = ...

// no footer

table.SetStyle(st.StyleCompactClassic)
fmt.Println(table.String())

Will output

UUID                                   NAME         NAMESPACE    STATUS
1aaf112f-c398-4fe8-a25b-638da8df372c   myname       my-ns        Ready

Very common table output style for various terminal applications.

This PR implements the sort interface for table.Body

You can call table.Body.SortByField(index) to sort Body.Cells by given field index using lexical order. or you can call table.Body.SortByFieldWithFunc(index, LessFunc) to sort Cells by given field index using your own LessFunc implementation.

Hi, when I try the example on Go 1.9.4, it returns these errors:

(unknown field 'Content' in struct literal of type simpletable.Cell)

EDIT: in the image, I tried changing Content to content on line 24, 25, and 26, this is why it's lowercase there

Hey Alex,

Thanks for this great library.

I am having an issue adding Span to the header. Any idea what I am doing wrong? I posted the error and code below.

Regards, Maruf
