I would also like the ability to wrap text for multiline columns. I want to be able to see all of my data without hovering over each cell to read the entire item.
Inability to right-align numbers and dates make this control virtually unusable for so many purposes. Clients just don't take well to seeing them left-aligned.
Also agree that there should be alignment options for column headers and contents. Trying to implement a PowerApp, this absence makes numbers or currency columns in particular look messy as is.
Agree with @OCV8 that the inability to right-align numeric fields is a huge hole with this component. I don't know why this does not have 100s or 1000s of up-votes.
Had to vote for this as well. It seems like such a no-brainer. Until the ability to format columns in a data table control is added it's useless for most of the use cases I have for it. I can't include anything with a description or notes because text doesn't wrap and columns can't be formatted individually. Even putting a formula into a column's "Text" control that displays currency doesn't allow me to format it; despite the formula appearing to be fine.
