在Golang中创建数组文字数组

How do I create an array of int arrays in Golang using slice literals?

I've tried

test := [][]int{[1,2,3],[1,2,3]}

and

type Test struct {
   foo [][]iint
}

bar := Test{foo: [[1,2,3], [1,2,3]]}

    You almost have the right thing however your syntax for the inner arrays is slightly off, needing curly braces like; test := [][]int{[]int{1,2,3},[]int{1,2,3}} or a slightly more concise version; test := [][]int{{1,2,3},{1,2,3}}

    The expression is called a 'composite literal' and you can read more about them here; https://golang.org/ref/spec#Composite_literals

    But as a basic rule of thumb, if you have nested structures, you have to use the syntax recursively. It's very verbose.
