+### MaxColumnLengthinDataTable
+
+Takes a datatable object and iterates through it to get the max length of the string columns - useful for data loads into a SQL Server table with fixed column widths by @SQLDBAWithABeard
+
+#### Snippet

+```json
+    "Max Length of Datatable": {
+        "prefix": "Max Length of Datatable",
+        "body": [

+            "foreach($$column in $$Columns) {",
+            "    $$max = 0",
+            "    foreach ($$a in $$datatable){",

 ### Parameter-Credential
 
 Add a `-Credential` parameter that supports a PSCredential object in a variable, `-Credential (Get-Credential)`, or `-Credential Username` (will prompt). Includes an empty PSCredential object as the default value but this is the first tabstop so pressing backspace after inserting the snippet removes it. by @omniomi
