一个关于jtable放置在jscrollpane的问题？

[hojialiang]

每当这样时，jtable的列宽度总是以jscrollpane的宽度等分，如何令jtable宽度大于jscrollpane？

[lianyunzxp]

我感觉好象jtable的宽度没法大于jscrollpane的宽度,大了岂不是出来滚动条了
如果你要是想改变jtable的列宽度
tbl.getColumnModel().getColumn(1).setWidth(100);//改变第一列的宽度

当然不是, 是 JTable 缺省的 resize 模式不一样.

void setAutoResizeMode(int mode)
Sets the table's auto resize mode when the table is resized.

static int AUTO_RESIZE_ALL_COLUMNS
During all resize operations, proportionately resize all columns.

static int AUTO_RESIZE_LAST_COLUMN
During all resize operations, apply adjustments to the last column only.

static int AUTO_RESIZE_NEXT_COLUMN
When a column is adjusted in the UI, adjust the next column the opposite way.

static int AUTO_RESIZE_OFF
Do not adjust column widths automatically; use a scrollbar.

static int AUTO_RESIZE_SUBSEQUENT_COLUMNS
During UI adjustment, change subsequent columns to preserve the total width; this is the default behavior.

剩下的就不用多说什么了.

另外: column 的宽度, 缺省情况下用的都是 TableColumn 的 PreferredSize
最好使用这个来确定宽度.
