描述

brief desc:
condition: width is not fixed px but %, result: columnWidth not correctly computed if table initialized hidden and then click somewhere to show it steps:

  1. html like this: <div ng-show='table.show'><div ui-grid='table.option' style="width: 100%"></div></div> <a ng-click='table.click()'></a>

2 .js $scope.table={ show: false, option:{ .... }, click:function(){this.show = true} }

  1. result: columnWidth value is NaN so that all the width defined in columnDefs doesn't work, the table css looks not correct, and api.core.refresh() doesn't make things work right.
  2. if the initial value of table.show is true, everything works fine.

研究方向
Investigate how ui grid calculates column widths when the grid container is initially hidden (ng show=false). The issue suggests that percentage widths are not computed correctly, resulting in NaN. Look into the grid's resize logic and initialization sequence in files like Grid.js or UiGridConstants.js. Check if the grid relies on container dimensions that are not available when hidden, and consider using a resize observer or recalculation on show.
