Tips for distinguishing individual rows within a table that includes rowspans?

Question

Tips for distinguishing individual rows within a table that includes rowspans?

My Vue application calculates a table with rowspans by using an algorithm based on a configuration file. This allows the application to render columns (and maintain their order) dynamically, depending on the calculated result.

For example, see the code snippet below:

<template>
  <table>
    <thead>
      <th>City</th>
      <th>Inhabitant</th>
      <th>House</th>
      <th>Room</th>
    </thead>
    <tbody>
      <tr v-for="(row, rowIndex) in tableMatrix" :key="rowIndex">
        <template v-for="(cell, columnIndex) in row" :key="columnIndex">
          <td v-if="cell.isCoveredByPreviousCell" style="display: none" />
          <td v-else :rowspan="cell.rowspan ?? 1">
            <template v-if="cell.content">
              {{ cell.content }}
            </template>
          </td>
        </template>
      </tr>
    </tbody>
  </table>
</template>

<script setup lang="ts">
import { ref, Ref } from 'vue';

interface Cell { isCoveredByPreviousCell: boolean; rowspan: number; content?: string; }

type TableMatrix = Cell[][];

const tableMatrix: Ref<TableMatrix> = ref([
  [
    { isCoveredByPreviousCell: false, rowspan: 5, content: "City 1" },
    { isCoveredByPreviousCell: false, rowspan: 4, content: "Inhabitant 1" },
    { isCoveredByPreviousCell: false, rowspan: 3, content: "House 1" },
    { isCoveredByPreviousCell: false, content: "Room 1" },
  ],
  // more rows...
])
</script>

<style>
table, th, td { border-collapse: collapse; border: 1px solid black; }
</style>

The output generated is correct, but I'm looking for ways to enhance the visual clarity of the table design. Zebra striping doesn't work in this case. One approach could be adding dividing rows with fixed heights and different background colors or increasing the bottom border width of row cells. When attempting to add

tr { border-bottom: 5px solid black; }

, the outcome changes as shown here:

I'd appreciate any suggestions or ideas you might have to improve the presentation of the table.

Answer №1

The issue at hand

The user (OP) is seeking a way to make the primary rows in a table stand out more prominently, specifically focusing on their height
Shown below is the image provided by the OP for reference: https://i.stack.imgur.com/oVSxp.png

The proposed resolution

One simple solution suggested involves adding a top border to these primary rows

<template>
  <table>
    <tr v-for="(row, rowIndex) in tableMatrix"
          :class="{split: isFullSplit(row)}"> ... </tr>
  </table>
</template>
<script setup lang="ts">
  function isFullSplit(row: Cell[]) {
    return row.every(c => !c.isCoveredByPreviousCell)
  }
</script>
<style>
  /* significant border-top for highlighting primary rows */
  tr:not(:first-child).split { border-top: 10px solid red; }
</style>

In considering your challenge, perhaps we can explore a different perspective:

Do the connections have to be in rows? You might consider using arrows to indicate connections between divs instead (see example code)

https://i.stack.imgur.com/0Hcgb.png

This approach mirrors what Google does on its Cloud Platform when faced with a similar issue. While not the most visually appealing diagram, it serves as an illustration. Alternatives could include straight lines with 90-degree turns or a uniform color scheme and/or dotted lines.

If you wrap your existing content in a border-span and align them vertically using tables, you'll find yourself closely resembling the example provided above – now just link those points together."

It appears that the issue lies in the transition from traditional rows and lines to nested tiles, which complicates the implementation of zebra stripes. To address this, it may be more effective to emphasize these tiles and their nesting levels by adjusting border styles accordingly. For example, using thicker borders between cities and thinner borders between rooms:

https://i.stack.imgur.com/UR5Vo.png

By modifying the vertical borders to form a '⊢' shape, the boundaries of the tiles become clearer. Introducing colors can also help differentiate structure from content:

https://i.stack.imgur.com/947iF.png

Doubling the border size further accentuates the structure, but compatibility with the rest of the layout must be considered:

https://i.stack.imgur.com/pfk0X.png

To determine the width of the top border for each row, you can find the index of the first data cell using the following logic:

const rowClasses = computed(() => tableMatrix.value.map(row => 'border-width-'+ (4 - row.findIndex(cell => !cell.isCoveredByPreviousCell))))

This value can then be applied as a class to each row in the layout.

In my view, utilizing rowspans in the code can result in a cluttered and confusing layout. The challenge lies in ensuring that two cells stacked on top of each other appear within the same row without actually being structured as such in the implementation. Any attempt to simulate this arrangement will likely lead to a messy solution.

From my perspective, a better approach would be to place these vertically aligned cells in the same table row and utilize CSS to position one above the other within the same cell. By applying

tr { border-bottom: 5px solid black; }

, you can achieve the desired visual result while maintaining a cleaner code structure.

Answer №5

If you're looking to create a table with zebra stripes, make sure each cell corresponds to the data you want to display. For example, for City 2, Inhabitant 1, House 1, and Room 1, ensure there is content in each cell. To achieve a zebra-striped effect, style each corresponding cell individually.

Optimize your code by avoiding messy rowspan usage in JavaScript; consider using HTML instead. Keeping your code concise is crucial for efficient coding practices.

For a zebra-striped table layout, here's a sample code snippet:

<template>
  <table>
    <thead>
      <th>City</th>
      <th>Inhabitant</th>
      <th>House</th>
      <th>Room</th>
    </thead>
    <tbody>
     <!-- Your data rendering logic here -->
    </tbody>
  </table>
</template>

<script setup lang="ts">
import { ref, Ref } from 'vue';

interface Cell { isCoveredByPreviousCell: boolean; rowspan: number; content?: string; }

type TableMatrix = Cell[][];

const tableMatrix: Ref<TableMatrix> = ref([
  <!-- Your data structure here -->
])
</script>
<style>
<!-- Your CSS styling for the table goes here -->
</style>

Here is my version of the comment implementation, featuring a blurred green zebra striping:

const data = [
  [{
      isCoveredByPreviousCell: false,
      rowspan: 5,
      content: "City 1"
    },
    {
      isCoveredByPreviousCell: false,
      rowspan: 4,
      content: "Inhabitant 1"
    },
    {
      isCoveredByPreviousCell: false,
      rowspan: 3,
      content: "House 1"
    },
    {
      isCoveredByPreviousCell: false,
      content: "Room 1"
    },
  ],
  [{
      isCoveredByPreviousCell: true
    },
    {
      isCoveredByPreviousCell: true
    },
    {
      isCoveredByPreviousCell: true
    },
    {
      isCoveredByPreviousCell: false,
      content: "Room 2"
    },
  ],
  // More data entries here...
];
// JavaScript logic for populating and styling tables

.as-console-wrapper { max-height: 44px; height: 44px; }

/* Zebra striping styles */
.zebra .even {
  background-color: white;
  color: white;
}

.zebra .odd {
  background-color: palegreen;
  color: palegreen;
}

/* Apply zebra style to specific elements */
.zebra th {
  background-color: white;
  color: white;
}

.zebra {
  border-collapse: collapse;
  border: 1px solid palegreen;
  position: absolute;
  z-index: 0;
  filter: blur(4px);
}

table:not(.zebra) {

  border: 1px solid palegreen;

}

table:not(.zebra) {
  border-collapse: collapse;
  border: 1px solid;
