LONDON, Sept 5 (Reuters) - Liz Truss will become Britain's next prime minister after winning a leadership race for the governing Conservative Party on Monday, vowing to press ahead with promised tax cuts and action to tackle a deepening energy and cost of living crisis.
After weeks of an often bad-tempered and divisive leadership contest, Truss, currently the foreign minister and the favourite to win, beat former finance minister Rishi Sunak in a vote of Conservative Party members, winning by 81,326 votes to 60,399.

"I will deliver a bold plan to cut taxes and grow our economy," Truss said after the result was announced. "I will deliver on the energy crisis, dealing with people's energy bills, but also dealing with the long-term issues we have on energy supply." read more
Truss takes over as the country faces a crunch on household finances, industrial unrest, a recession and war in Europe, where Britain has been a leading backer of Ukraine. She appeared to rule out another national election before 2024, when she promised to deliver a great victory for her party.

然后输出的是错误的行信息，如何获取像P7/L16或P7/R17这样的索引条目页面样式？
谢谢！

参照@Cicada的笔记，我通过 重置了每页的行数\usepackage{etoolbox}\preto{\sffamily}{\resetlinenumber}，并使用 引入了 lineno 包跑步标签。然后索引中的行号显示几乎正确，但不正确。
输出的行号是该条目所在段落第一行的行号：
索引输出如下：
那么为什么这么奇怪？
