我創(chuàng)建了表格行標(biāo)題，如下所示。我想在這 4 個(gè)標(biāo)題中創(chuàng)建一個(gè)矩形 svg 框。我無(wú)法確定段落高度，因此無(wú)法創(chuàng)建完全適合段落的框。這是我的代碼let svg = d3.select("body").append("svg").attr("width", 1000).attr("height", 1000);let text=["Who will win the election. Trump or Biden?","Data Analysis","Javascript","Compare Performance of S&P 500 Index against other Indices"  ]svg.selectAll("boxestext")    .data([0,100,200,300])    .enter()    .append("foreignObject")    .attr("width", (d, i) => 100 )    .attr("height", 200)    .attr("x",(d, i) => d)    .attr("y",0)    .attr("class", "boxes")    .append("xhtml:body")    .style("font", 50)    .html((d,i)=>"<p>"+text[i]+"</p>") https://codepen.io/zubair57/pen/MWeXPqX
