How can I get my HTML table to be shown as supposed to?

Summary

The issue at hand is with HTML table rendering, where cells are occupying several rows and/or columns, causing the table to not be displayed as intended. The problem lies in the way browsers render tables with colspan and rowspan attributes.

Root Cause

The root cause of this issue is due to the following reasons:

  • Insufficient table rows: The table does not have enough rows to accommodate the rowspan attribute, causing the browser to render the table incorrectly.
  • Browser rendering quirks: Different browsers have different rendering quirks when it comes to HTML tables, which can lead to inconsistent results.

Why This Happens in Real Systems

This issue can occur in real systems due to:

  • Complex table structures: Tables with multiple colspan and rowspan attributes can be difficult for browsers to render correctly.
  • Dynamic table generation: Tables generated dynamically using JavaScript or other programming languages can lead to rendering issues if not properly constructed.

Real-World Impact

The impact of this issue can be significant, including:

  • Incorrect data display: Tables not rendering correctly can lead to incorrect data being displayed, which can have serious consequences in certain applications.
  • User experience issues: Tables that are not rendered correctly can be difficult for users to read and understand, leading to a poor user experience.

Example or Code

1 2 3 4 5 6 7 8 9
5x5 4x2
6 7 8 9
6 7 8 9
6 7 8 9
1 2 3 4 5 6 7 8 9

How Senior Engineers Fix It

Senior engineers can fix this issue by:

  • Adding extra table rows: Adding extra table rows to accommodate the rowspan attribute can help browsers render the table correctly.
  • Using CSS styling: Using CSS styling to control the layout of the table can help ensure consistent rendering across different browsers.
  • Testing and validation: Thoroughly testing and validating the table structure can help identify and fix rendering issues.

Why Juniors Miss It

Junior engineers may miss this issue due to:

  • Lack of experience: Limited experience with HTML tables and browser rendering quirks can make it difficult for junior engineers to identify and fix rendering issues.
  • Insufficient testing: Inadequate testing and validation of the table structure can lead to rendering issues going unnoticed.
  • Overreliance on browsers: Relying too heavily on browsers to render tables correctly can lead to issues when browsers behave differently than expected.
