My code:

t := table.NewWriter()
style := table.Style{
	Name:    "my-style",
}
t.SetStyle(style)
t.SetOutputMirror(os.Stdout)
t.AppendHeader(table.Row{"#", "Name", "Address", "Phone", "Birthday"})

for i, info := range data.Items {
	t.AppendRows([]table.Row{{i, info.Name, info.Address, info.Phone, info.Birthday}})
}
t.AppendSeparator()
t.AppendFooter(table.Row{"Total", len(data.Items), "", ""})
t.Render()

Hey thanks for reporting this. I've fixed the code that caused the panic and created a new tag v6.2.2 with the fix.

However, I should also note that if you want to customize the table styles, you have to do it completely instead of just setting the Name. Another alternative is to use an existing style with all the values, and then start modifying it to your liking.

// one approach
tw := table.NewWriter()
style := table.StyleDefault
style.Name = "my-style"
// more customizations
tw.SetStyle(style)

// another approach
table.Style().Name = "my-style"
// the call into Style() will init it with StyleDefault if there is no style set currently
