如何在一个被修剪的textField底部对齐textFields？

Question

我在使用Jasper报告时遇到了问题。

在我的报告中，我正在尝试对齐textFields，如：

${name}                      ${field1}
${age}                       ${field2}
${address}                   ${field3}

textField ${name}能够stretchWithOverflow导致它与${field1}重对。

如果textField ${name}延伸，我希望获得${field1}与${name}上的最后一行对齐的结果。

${name}                      
${name}(stretched)           ${field1}
${age}                       ${field2}
${address}                   ${field3}

我读了很多论坛但找不到解决方案。

您可以使用positionType="FixRelativeToBottom"属性

来实现此目的

注意：如果您有多个字段在相同的细节范围内拉伸，它会变得更复杂，在这些情况下，您可能需要使用子报告来获得正确的布局。
