Kuix TableLayout bug说明

    实际上用过TableLayout来作表格的人估计都碰到过,TableLayout有根据cell内容长度自动扩展的特点(要保证表格不变形,只能自己断行),如果cell合并,当合并cell太长时,自动扩展所在列的宽度,而不是根据合并后的列宽度来扩展,例子如下:

<screen title="TableLayout Demo">
	<scrollpane scrollbar="both">
	<container style="layout:tablelayout;gap:1 1;border:1 1 1 1;border-color:red;bg-color:red;font-size:large">
	<text class="child1" style="min-size:30 0">姓名</text>
	<text class="child1" style="min-size:50 0">部门</text><break/>
	<text class="child1" style="span:2 1">我们是更加重视下拉</text>
	</container>
	</scrollpane>
	<screenfirstmenu onAction="back">Back</screenfirstmenu>
	<screenSecondMenu onAction="exit">Exit</screenSecondMenu>
</screen>

     第二行采用合并单元格,结果第一列被迫扩展到必须包含合并cell文字的长度,效果如下图:

    实际上在计算每列最小宽度时,作者偷了个懒,直接用所在列中最大长度的widget作为列宽度,而没有计算它合并的列,虽然实际上它确实对合并列做了一些处理.有兴趣的人可以看看它的align函数,这个函数可不是对齐,是计算每一列宽度

	/**
	 * shappycom
	 * @param first 链表
	 * @param values 返回值(width/height)
	 * @param weights
	 * @param horizontal
	 * @param fullSize 减去边界和间隔后可用的长度
	 */
	private static final void align(Metrics first, int[] values, int[] weights, boolean horizontal, int fullSize) {
		for (int size = 1, next = 0; size != 0; size = next, next = 0) {
			for (Metrics metrics = first; metrics != null; metrics = metrics.next) {
				Span span = metrics.widget.getSpan();
				int orientedSpan = horizontal ? span.colspan : span.rowspan;
				if (orientedSpan == size) {
					
					int value;
					if (weights != null) {
						value = horizontal ? metrics.width : metrics.height;
					} else {
						Weight weight = metrics.widget.getWeight();
						value = horizontal ? weight.weightx : weight.weighty;
					}
					
					int index = horizontal ? metrics.x : metrics.y;
					if (weights != null && weights[index] != 0) {
						value = MathFP.toInt(MathFP.mul(weights[index], MathFP.toFP(fullSize)));
					}
					
					
					values[index] = Math.max(values[index], value);
					
				} else if ((orientedSpan > size) && ((next == 0) || (next > orientedSpan))) {
					next = orientedSpan;
				}
			}
		}
	}
