使用style="text-anchor:middle"更新您的html，并使用span标记

html: '<span style="text-anchor:middle">My custom label</span><br><span style="text-anchor:middle">My Label Data</span><br><span style="text-anchor:middle">Another Label Data</span><br><span style="text-anchor:middle">How to apply text align:center property those text</span>',
