I found a few small mistakes when exporting with scene composer.
Using: LibGDX version 1.11.0

Fixes:

• Duplicate .setTouchable gets added if actor.touchable != Touchable.childrenOnly and actor.visible is false.
• .setTouchable gets passed a boolean a few times (e.g. line 110) but requires Touchable type
• .preferredSize should be .prefSize
• .preferredWidth should be .prefWidth
• .preferredHeight should be .prefHeight
• .setPreferredRows should be .setPrefRows
• .setSplit should be .setSplitAmount
• .align should be .rowAlign on Line 824
• .align should be .columnAlign on Line 1069
• .setScrollBarsVisible should be .setScrollbarsVisible
• .setName's param should have quotation marks on SimTable
• .fillX and .fillY shouldn't have boolean params

Note: LibGDX itself has some inconsistent naming.

• fadeScrollBars
• setScrollbarsVisible
• setScrollBarTouch
