Make a table fast with repeaters, automate position for labels inside repeater

I need to prototype a big amount of tables that use repeaters and are changing constantly.
After a couple of minutes making the table with repeaters, the client see it and then request me to move or add new columns and it takes even more time to move all widgets (columns) to the right and insert the new one in the perfect position and then repeat that same process but in the header.
Is there any way to make this process a little easer?

  • Maybe someway to move all label widgets to right when I change the size of a column in the middle?
  • Maybe puting all the labels in the row in random possition and in the onload event assign the possitions bassed on their widths with the moveto action?

Thank you.
