javascript - How to scale the column width of a Yii2 table and keep it unchanged after the page is refreshed?

1. The list generated by Yii2 DynaGrid plug-in can manually drag the width of each column, but how to save it after dragging? After refreshing the page, the width will still be the same as the dragging stop.

The main code is as follows: (controlled by the two classes rc-table-resizing and rc-column-resizing)

Note: The following is the source code, it cannot be changed and needs to be rewritten.

<code> ResizableColumns.prototype.pointerdown = function(e) {
      var $currentGrip, $leftColumn, $ownerDocument, $rightColumn, newWidths, startPosition, widths;
      e.preventDefault();
      $ownerDocument = $(e.currentTarget.ownerDocument);
      startPosition = pointerX(e);
      $currentGrip = $(e.currentTarget);
      $leftColumn = $currentGrip.data('th');
      $rightColumn = this.$tableHeaders.eq(this.$tableHeaders.index($leftColumn) + 1);
      widths = {
        left: parseWidth($leftColumn[0]),
        right: parseWidth($rightColumn[0])
      };
      newWidths = {
        left: widths.left,
        right: widths.right
      };
      this.$handleContainer.add(this.$table).addClass('rc-table-resizing');
      $leftColumn.add($rightColumn).add($currentGrip).addClass('rc-column-resizing');
      this.triggerEvent('column:resize:start', [$leftColumn, $rightColumn, newWidths.left, newWidths.right], e);
      $ownerDocument.on('mousemove.rc touchmove.rc', (function(_this) {
        return function(e) {
          var difference;
          difference = (pointerX(e) - startPosition) / _this.$table.width() * 100;
          setWidth($leftColumn[0], newWidths.left = _this.constrainWidth(widths.left + difference));
          setWidth($rightColumn[0], newWidths.right = _this.constrainWidth(widths.right - difference));
          if (_this.options.syncHandlers != null) {
            _this.syncHandleWidths();
          }
          return _this.triggerEvent('column:resize', [$leftColumn, $rightColumn, newWidths.left, newWidths.right], e);
        };
      })(this));
      return $ownerDocument.one('mouseup touchend', (function(_this) {
        return function() {
          $ownerDocument.off('mousemove.rc touchmove.rc');
          _this.$handleContainer.add(_this.$table).removeClass('rc-table-resizing');
          $leftColumn.add($rightColumn).add($currentGrip).removeClass('rc-column-resizing');
          _this.syncHandleWidths();
          _this.saveColumnWidths();
          return _this.triggerEvent('column:resize:stop', [$leftColumn, $rightColumn, newWidths.left, newWidths.right], e);
        };
      })(this));
    };

    return ResizableColumns;

This is controlled by css. You can set a session to save the width of your list. When refreshing, you can use js to assign the value to css.

What you said above is correct
