body { margin:0; padding: 0; display: flex; flex-wrap: wrap; height: 930px; } .table-container{ display: flex; justify-content: center; align-items: center; border-collapse: collapse; border: 2px solid #999; } .graph-container{ flex: 1; padding: 10px; background-color: #f0f0f0; box-sizing: border-box; display: flex; flex-wrap: wrap; align-items: left; justify-content: left; } .graph{ width: 45%; height: 300px; margin: 10px; background-color: #ccc; border: 1px solid #999; } @media screen and (max-width: 1200px){ .graph{ width: 45%; } } @media screen and (max-width: 800px){ .graph{ width:90%; } 修改代码 让表格容器占页面的三分之一

可以将.table-container的flex属性改为flex: 1 0 33.33%;，这样就可以让表格容器占据页面的三分之一了。代码如下：

body {
  margin: 0;
  padding: 0;
  display: flex;
  flex-wrap: wrap;
  height: 930px;
}

.table-container {
  display: flex;
  justify-content: center;
  align-items: center;
  border-collapse: collapse;
  border: 2px solid #999;
  flex: 1 0 33.33%;
}

.graph-container {
  flex: 1;
  padding: 10px;
  background-color: #f0f0f0;
  box-sizing: border-box;
  display: flex;
  flex-wrap: wrap;
  align-items: left;
  justify-content: left;
}

.graph {
  width: 45%;
  height: 300px;
  margin: 10px;
  background-color: #ccc;
  border: 1px solid #999;
}

@media screen and (max-width: 1200px) {
  .graph {
    width: 45%;
  }
}

@media screen and (max-width: 800px) {
  .graph {
    width: 90%;
  }
}
