Summary of Changes
Hello @yoyo837, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request refines the logic for calculating column widths within a virtual table component. The update ensures that column dimensions properly account for minimum width constraints, leading to more robust and predictable table layouts.
Highlights
- Column Width Calculation: Updated the column width calculation in src/VirtualTable/BodyGrid.tsx to consider
minWidthin addition towidth, ensuring that the final column width is at least the specified minimum width.

Code Review
This pull request introduces support for minWidth on columns in the virtualized table, which is a valuable addition. The implementation correctly uses Math.max to determine the final column width. However, I've identified a potential issue in how column width is parsed when it's a string containing units (e.g., '100px'). The current approach may result in an incorrect width of 0. I've provided a suggestion to use parseFloat for more robust parsing.
| total += width as number; | ||
| return [key, width as number, total]; | ||
| return flattenColumns.map(({ width, minWidth, key }) => { | ||
| const finalWidth = Math.max((width as number) || 0, (minWidth as number) || 0); |

The expression (width as number) || 0 is not robust enough to handle all possible string values for width. If width is a string containing units, like '100px', the Number(width) conversion at runtime will result in NaN. Consequently, NaN || 0 evaluates to 0, causing the column's width to be incorrectly set to zero.
To ensure widths are parsed correctly, even when they include units like px, it is better to use parseFloat. This function will extract the numerical value from the string, providing a more reliable width calculation.
const finalWidth = Math.max(parseFloat(String(width)) || 0, (minWidth as number) || 0);
