如何将一个节点定位在另一个节点下方，以便较短的节点从较宽的节点开始（而不是居中）？

Question

我需要底部节点从它们各自的顶部节点开始，而不是位于它们下方的中心。

输出：

代码：

\begin{tikzpicture}
\node[align=left,draw=black,rounded corners](colOne_rowOne)
{
this is line 1\\
this is line 2, this is line 2
};
\node[below=of colOne_rowOne,align=left,draw=black,rounded corners](colOne_rowTwo)
{
this is line
};
\node[right=of colOne_rowOne,align=left,draw=black,rounded corners](colTwo_rowOne)
{
this is line 1\\
this is line 2, this is line 2
};
\node[below=of colTwo_rowOne,align=left,draw=black,rounded corners](colTwo_rowTwo)
{
this is line
};
\end{tikzpicture}

虽然@Zarko 的答案在这种情况下有效，但我认为使用锚点更清晰：

\begin{tikzpicture}[box/.style={align=left,draw=black,rounded corners}]
    \node[box](colOne_rowOne)
    {
        this is line 1\\
        this is line 2, this is line 2
    };
    \node[box, below=of colOne_rowOne.south west, anchor=north west](colOne_rowTwo)
    {
        this is west-aligned
    };
    \node[box, right=of colOne_rowOne](colTwo_rowOne)
    {
        this is line 1\\
        this is line 2, this is line 2
    };
    \node[box, below=of colTwo_rowOne.south east, anchor=north east](colTwo_rowTwo)
    {
        this is east-aligned
    };
\end{tikzpicture}

锚点就是为这个任务而设的：它们告诉当前节点的哪个点应该位于给定的坐标处。然后你可以使用键node distance来改变节点之间的距离。

重建缺失的序言并不好玩：它包含了图像绘制的重要信息......

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{positioning}

\begin{document}
    \begin{tikzpicture}[
node distance = 3mm and 0mm,
box/.style = {shape=rectangle, draw, rounded corners, align=left}
                        ]
\node[box](colOne_rowOne)
        {
        this is line 1\\
        this is line 2, this is line 2
        };
\node[box, below right=of colOne_rowOne.south west](colOne_rowTwo)
        {
        this is line
        };
\node[box, right=6mm of colOne_rowOne](colTwo_rowOne)
        {
        this is line 1\\
        this is line 2, this is line 2
        };
\node[box, below right=of colTwo_rowOne.south west] (colTwo_rowTwo)
        {
        this is line
        };
    \end{tikzpicture}
\end{document}
